What I really need is some way for Fail2Ban to manage its ban list, effectively, remotely. Isn't that just directing traffic to the appropriate service, which then handles any authentication and rejection? I used following guides to finally come up with this: https://www.the-lazy-dev.com/en/install-fail2ban-with-docker/ - iptable commands etc .. Hope this helps some one like me who is trying to solve the issues they face with fail2ban and docker networks :). Super secret stuff: I'm not working on v2 anymore, and instead slowly working on v3. The only issue is that docker sort of bypasses all iptables entries, fail2ban makes the entry but those are ignored by docker, resulting in having the correct rule in iptables or ufw, but not actually blocking the IP. real_ip_header CF-Connecting-IP; hope this can be useful. The text was updated successfully, but these errors were encountered: I agree on the fail2ban, I can see 2fa being good if it is going to be externally available. The condition is further split into the source, and the destination. By taking a look at the variables and patterns within the /etc/fail2ban/jail.local file, and the files it depends on within the /etc/fail2ban/filter.d and /etc/fail2ban/action.d directories, you can find many pieces to tweak and change as your needs evolve. actionban = iptables -I DOCKER-USER -s -j DROP, actionunban = iptables -D DOCKER-USER -s -j DROP, Actually below the above to be correct after seeing https://docs.rackspace.com/support/how-to/block-an-ip-address-on-a-Linux-server/. I have a question about @mastan30 solution: fail2ban-docker requires that fail2ban itself has to (or must not) be installed on the host machine (dont think, iti is in the container)? To make this information appear in the logs of Nginx, modify nginx.conf to include the following directives in your http block. Hello, on host can be configured with geoip2 , stream I have read it could be possible, how? I have configured the fail2ban service - which is located at the webserver - to read the right entrys of my log to get the outsiders IP and blocks it. Docker installs two custom chains named DOCKER-USER and DOCKER. In your instructions, you mount the NPM files as /data/logs and mount it to /log/npm, but in this blog post, the author specifically mentions "Ensure that you properly bind mount the logs at /data/logs of your NPM reverse proxy into the Fail2ban docker container at /var/log/npm. You'll also need to look up how to block http/https connections based on a set of ip addresses. But is the regex in the filter.d/npm-docker.conf good for this? sender = fail2ban@localhost, setup postfix as per here: Along banning failed attempts for n-p-m I also ban failed ssh log ins. The findtime specifies an amount of time in seconds and the maxretry directive indicates the number of attempts to be tolerated within that time. WebAs I started trying different settings to get one of services to work I changed something and am now unable to access the webUI. In terminal: $ sudo apt install nginx Check to see if Nginx is running. It works form me. You can follow this guide to configure password protection for your Nginx server. Because this also modifies the chains, I had to re-define it as well. To properly block offenders, configure the proxy and Nginx to pass and receive the visitors IP address. Forward port: LAN port number of your app/service. But is the regex in the filter.d/npm-docker.conf good for this? WebFail2Ban is a wonderful tool for managing failed authentication or usage attempts for anything public facing. Adding the fallback files seems useful to me. nice tutorial but despite following almost everything my fail2ban status is different then the one is give in this tutorial as example. The log shows "failed to execute ban jail" and "error banning" despite the ban actually happening (probably at the cloudflare level. Using Fail2ban behind a proxy requires additional configuration to block the IP address of offenders. Multiple applications/containers may need to have fail2ban, but only one instance can run on a system since it is playing with iptables rules. I mean, If you want yo give up all your data just have a facebook and tik tok account, post everything you do and write online and be done with it. To learn more, see our tips on writing great answers. I know there is already an option to "block common exploirts" but I'm not sure what that actually does, and fail2ban is quite a robust way of dealing with attacks. Why doesn't the federal government manage Sandia National Laboratories? And those of us with that experience can easily tweak f2b to our liking. I would rank fail2ban as a primary concern and 2fa as a nice to have. Should be usually the case automatically, if you are not using Cloudflare or your service is using custom headers. I'd suggest blocking up ranges for china/Russia/India/ and Brazil. Setting up fail2ban is also a bit more advanced then firing up the nginx-proxy-manager container and using a UI to easily configure subdomains. How would fail2ban work on a reverse proxy server? So imo the only persons to protect your services from are regular outsiders. I am definitely on your side when learning new things not automatically including Cloudflare. We are not affiliated with GitHub, Inc. or with any developers who use GitHub for their projects. We can create an [nginx-noscript] jail to ban clients that are searching for scripts on the website to execute and exploit. Hi, thank you so much for the great guide! So hardening and securing my server and services was a non issue. I'm curious to get this working, but may actually try CrowdSec instead, since the developers officially support the integration into NPM. Authelia itself doesnt require a LDAP server or its own mysql database, it can use built in single file equivalents just fine for small personal installations. Having f2b inside the npm container and pre-configured, similiar to the linuxio container, gives end users without experience in building jails and filters an extra layer of security. Your tutorial was great! @jellingwood I consider myself tech savvy, especially in the IT security field due to my day job. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Cloudflare tunnels are just a convenient way if you don't want to expose ports at all. This will allow Nginx to block IPs that Fail2ban identifies from the Nginx error log file. This is less of an issue with web server logins though if you are able to maintain shell access, since you can always manually reverse the ban. I am using the current LTS Ubuntu distribution 16.04 running in the cloud on a DigitalOcean Droplet. Next, we can copy the apache-badbots.conf file to use with Nginx. According to https://www.home-assistant.io/docs/ecosystem/nginx/, it seems that you need to enable WebSocket support. The main one we care about right now is INPUT, which is checked on every packet a host receives. So I have 2 "working" iterations, and need to figure out the best from each and begin to really understand what I'm doing, rather than blindly copying others' logs. Regarding Cloudflare v4 API you have to troubleshoot. Depends. i.e. I just wrote up my fix on this stackoverflow answer, and itd be great if you could update that section section of your article to help people that are still finding it useful (like I did) all these years later. Each chain also has a name. The value of the header will be set to the visitors IP address. When users repeatedly fail to authenticate to a service (or engage in other suspicious activity), fail2ban can issue a temporary bans on the offending IP address by dynamically modifying the running firewall policy. I needed the latest features such as the ability to forward HTTPS enabled sites. Looking at the logs, it makes sense, because my public IP is now what NPM is using to make the decision, and that's not a Cloudflare IP. Each rule basically has two main parts: the condition, and the action. Otherwise, anyone that knows your WAN IP, can just directly communicate with your server and bypass Cloudflare. The script works for me. You signed in with another tab or window. So, is there a way to setup and detect failed login attemps of my webservices from my proxy server and if so, do youve got a hint? Some update on fail2ban, since I don't see this happening anytime soon, I created a fail2ban filter myself. And to be more precise, it's not really NPM itself, but the services it is proxying. Once these are set, run the docker compose and check if the container is up and running or not. The next part is setting up various sites for NginX to proxy. Just because we are on selfhosted doesn't mean EVERYTHING needs to be selfhosted. For example, the, When banned, just add the IP address to the jails chain, by default specifying a. Now that NginX Proxy Manager is up and running, let's setup a site. I followed the guide that @mastan30 posted and observed a successful ban (though 24 hours after 3 tries is a bit long, so I have to figure out how to un-ban myself). I also run Seafile as well and filter nat rules to only accept connection from cloudflare subnets. to your account. However, by default, its not without its drawbacks: Fail2Ban uses iptables How would I easily check if my server is setup to only allow cloudflare ips? First, create a new jail: This jail will monitor Nginxs error log and perform the actions defined below: The ban action will take the IP address that matches the jail rules (based on max retry and findtime), prefix it with deny, and add it to the deny.conf file. Based on matches, it is able to ban ip addresses for a configured time period. In this case, the action is proxy-iptables (which is what I called the file, proxy-iptables.conf), and everything after it in [ ] brackets are the parameters. A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control. My mail host has IMAP and POP proxied, meaning their bans need to be put on the proxy. I've got a few things running behind nginx proxy manager and they all work because the basic http (s)://IP:port request locally auto loads the desired location. But with nginx-proxy-manager the primary attack vector in to someones network iswellnginx-proxy-manager! Indeed, and a big single point of failure. And even tho I didn't set up telegram notifications, I get errors about that too. Your blog post seems exactly what I'm looking for, but I'm not sure what to do about this little piece: If you are using Cloudflare proxy, ensure that your setup only accepts requests coming from the Cloudflare CDN network by whitelisting Cloudflare's IPv4 and IPv6 addresses on your server for TCP/80 (HTTP) and TCP/443 (HTTPS). Yep. It is a few months out of date. Yes fail2ban would be the cherry on the top! Proxying Site Traffic with NginX Proxy Manager. How does a fan in a turbofan engine suck air in? --The same result happens if I comment out the line "logpath - /var/log/npm/*.log". Just Google another fail2ban tutorial, and you'll get a much better understanding. Setting up fail2ban to monitor Nginx logs is fairly easy using the some of included configuration filters and some we will create ourselves. @kmanwar89 100 % agree - > On the other hand, f2b is easy to add to the docker container. Bitwarden is a password manager which uses a server which can be To exclude the complexities of web service setup from the issues of configuring the reverse proxy, I have set up web servers with static content. You get paid; we donate to tech nonprofits. All rights belong to their respective owners. edit: most of your issues stem from having different paths / container / filter names imho, set it up exactly as I posted as that works to try it out, and then you can start adjusting paths and file locations and container names provided you change them in all relevant places. The above filter and jail are working for me, I managed to block myself. Tldr: Don't use Cloudflare for everything. It's the configuration of it that would be hard for the average joe. You can add additional IP addresses or networks delimited by a space, to the existing list: Another item that you may want to adjust is the bantime, which controls how many seconds an offending member is banned for.

I believe I have configured my firewall appropriately to drop any non-cloudflare external ips, but I just want a simple way to test that belief. https://www.fail2ban.org/wiki/index.php/Main_Page, https://forums.unraid.net/topic/76460-support-djoss-nginx-proxy-manager/, https://github.com/crazy-max/docker-fail2ban, https://www.the-lazy-dev.com/en/install-fail2ban-with-docker/, "iptables: No chain/target/match by that name", fail2ban with docker(host mode networking) is making iptables entry but not stopping connections, Malware Sites access from Nginx Proxy Manager, https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html, https://www.home-assistant.io/integrations/http/#trusted_proxies, in /etc/docker/daemon.json - you need to add option "iptables": true, you need to be sure docker create chain in iptables DOCKER-USER, for fail2ban ( docker port ) use SINGLE PORT ONLY - custom. Requests coming from the Internet will hit the proxy server (HAProxy), which analyzes the request and forwards it on to the appropriate server (Nginx). I am having trouble here with the iptables rules i.e. i.e jail.d will have npm-docker.local,emby.local, filter.d will have npm-docker.conf,emby.conf and filter.d will have docker-action.conf,emby-action.conf respectively . We can use this file as-is, but we will copy it to a new name for clarity. in this file fail2ban/data/jail.d/npm-docker.local I also added a deny rule in nginx conf to deny the Chinese IP and a GeoIP restriction, but I still have these noproxy bans. It seems to me that goes against what , at least I, self host for. You could also use the action_mwl action, which does the same thing, but also includes the offending log lines that triggered the ban: Now that you have some of the general fail2ban settings in place, we can concentrate on enabling some Nginx-specific jails that will monitor our web server logs for specific behavior patterns. Just for a little background if youre not aware, iptables is a utility for running packet filtering and NAT on Linux. I switched away from that docker container actually simply because it wasn't up-to-date enough for me. After you have surpassed the limit, you should be banned and unable to access the site. You may also have to adjust the config of HA. This one mixes too many things together. Should I be worried? as in example? Im at a loss how anyone even considers, much less use Cloudflare tunnels. Just neglect the cloudflare-apiv4 action.d and only rely on banning with iptables. This tells Nginx to grab the IP address from the X-Forwarded-For header when it comes from the IP address specified in the set_real_ip_from value. How would fail2ban work on a reverse proxy server? I am behind Cloudflare and they actively protect against DoS, right? This varies based on your Linux distribution, but for most people, if you look in /etc/apache2, you should be able to search to find the line:.

Thanks! Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. WebThe fail2ban service is useful for protecting login entry points. Welcome to your friendly /r/homelab, where techies and sysadmin from everywhere are welcome to share their labs, projects, builds, etc. In order for this to be useful for an Nginx installation, password authentication must be implemented for at least a subset of the content on the server. You'll also need to look up how to block http/https connections based on a set of ip addresses. Isn't that just directing traffic to the appropriate service, which then handles any authentication and rejection?

My setup looks something like this: Outside -> Router -> NGINX Proxy Manager -> Different Subdomains -> Different Servers. Connections to the frontend show the visitors IP address, while connections made by HAProxy to the backends use HAProxys IP address. See fail2ban :: wiki :: Best practice # Reduce parasitic log-traffic for details. I added an access list in NPM that uses the Cloudflare IPs, but when I added this bit from the next little warning: real_ip_header CF-Connecting-IP;, I got 403 on all requests.
