NPMplus

This project comes as a pre-built docker image that enables you to easily forward to your websites running at home or otherwise, including free TLS, without having to know too much about Nginx or Certbot.

• Quick Setup

Note: Reloading the NPMplus UI can cause a 502 error. See #241.
Note: NO armv7, route53 and aws cloudfront ip ranges support.
Note: add net.ipv4.ip_unprivileged_port_start=0 at the end of /etc/sysctl.conf to support PUID/PGID in network mode host.
Note: If you don't use network mode host, which I don't recommend, don't forget to expose port 443 on tcp AND udp (http3/quic needs udp).
Note: If you don't use network mode host, which I don't recommend, don't forget to enable IPv6 in Docker, see here, you only need to follow step one and two before deploying NPMplus!
Note: Don't forget to open Port 80 (tcp) and 443 (tcp AND udp, http3/quic needs udp) in your firewall (because of network mode host, you also need to open this ports in ufw, if you use ufw).
Note: ModSecurity overblocking (403 Error)? Please see /opt/npm/etc/modsecurity, if you also use CRS please see here.
Note: Other Databases like MariaDB may work, but are unsupported.
Note: access.log/stream.log, logrotate and goaccess are NOT enabled by default bceuase of GDPR, you can enable them in the compose.yaml.

Project Goal

I created this project to fill a personal need to provide users with an easy way to accomplish reverse proxying hosts with TLS termination and it had to be so easy that a monkey could do it. This goal hasn't changed. While there might be advanced options they are optional and the project should be as simple as possible so that the barrier for entry here is low.

Features

• Beautiful and Secure Admin Interface based on Tabler
• Easily create forwarding domains, redirections, streams and 404 hosts without knowing anything about Nginx
• Free trusted TLS certificates using Certbot (Let's Encrypt/other CAs) or provide your own custom TLS certificates
• Access Lists and basic HTTP Authentication for your hosts
• Advanced Nginx configuration available for super users
• User management, permissions and audit log

List of new features

• Supports HTTP/3 (QUIC) protocol.
• Supports CrowdSec IPS. Please see here to enable it.
• goaccess included, see compose.yaml to enable, runs by default on https://:91 (nginx config from here)
• Supports ModSecurity, with coreruleset as an option. You can configure ModSecurity/coreruleset by editing the files in the /opt/npm/etc/modsecurity folder.
  • If the core ruleset blocks valid requests, please check the /opt/npm/etc/modsecurity/crs-setup.conf file.
  • Try to whitelist the Content-Type you are sending (for example, application/activity+json for Mastodon and application/dns-message for DoH).
  • Try to whitelist the HTTP request method you are using (for example, PUT is blocked by default, which also affects NPM).

• Darkmode button in the footer for comfortable viewing (CSS done by @theraw)
• Fixes proxy to https origin when the origin only accepts TLSv1.3
• Only enables TLSv1.2 and TLSv1.3 protocols
• Faster creation of TLS certificates can be achieved by eliminating unnecessary Nginx reloads and configuration creations.
• Uses OCSP Stapling for enhanced security
• Resolved dnspod plugin issue
  • To migrate manually, delete all dnspod certs and recreate them OR change the credentials file as per the template given here
• Smaller docker image with alpine-based distribution
• Admin backend interface runs with https
• Default page also runs with https
• Uses fancyindex if used as webserver
• Exposes INTERNAL backend api only to localhost
• Basic security headers are added if you enable HSTS (HSTS has always subdomains and preload enabled)
• access.log is disabled by default, unified and moved to /opt/npm/nginx/access.log
• Error Log written to console
• Server response header hidden
• PHP 8.2/8.3 optional, with option to add extensions; available packages can added using envs in the compose file
• Allows different acme servers/certbot config file (/opt/npm/tls/certbot/config.ini)
• Supports up to 99 domains per cert
• Brotli compression can be enabled
• HTTP/2 always enabled with fixed upload
• Allows infinite upload size
• Automatic database vacuum (only sqlite)
• Automatic cleaning of old certbot certs (set FULLCLEAN to true)
• Password reset (only sqlite) using docker exec -it npmplus password-reset.js USER_EMAIL PASSWORD
• Supports TLS for MariaDB/MySQL; set DB_MYSQL_TLS env to true. Self-signed certificates can be uploaded to /opt/npm/etc/npm/ca.crt and DB_MYSQL_CA set to /data/etc/npm/ca.crt (not tested, unsupported)
• Supports PUID/PGID in network mode host; add net.ipv4.ip_unprivileged_port_start=0 at the end of /etc/sysctl.conf
• Option to set IP bindings for multiple instances in network mode host
• Option to change backend port
• multi lang support, if you want to add an language, see this commit as an example: https://github.com/ZoeyVid/NPMplus/commit/a026b42329f66b89fe1fbe5e6034df5d3fc2e11f
• See the composefile for all available options
• If you want to redirect all HTTP traffic to HTTPS, you can use the compose.override.yaml file.

migration

• NOTE: migrating back to the original is not possible, so make first a backup before migration, so you can use the backup to switch back
• please delete all dnspod certs and recreate them after migration OR you manually change the credentialsfile (see here for the template)
• stop nginx-proxy-manager download the latest compose.yaml, adjust your paths (of /etc/letsencrypt and /data) to the ones you used with nginx-proxy-manager and adjust the env of the compose file how you like it and then deploy it
• you can now remove the /etc/letsencrypt mount, since it was moved to /data while migration and redeploy the compose file
• since this fork has dependency on network_mode: host, please don't forget to open port 80/tcp, 443/tcp and 443/udp (and maybe 81/tcp) in your firewall
• since many buttons changed, please edit every host you have and click save. (Please also resave it, if all buttons/values are fine, to update the host config to fully fit the NPMplus template)
• maybe setup crowdsec (see below)
• please report all (migration) issues you may have

Quick Setup

1. Install Docker and Docker Compose (or portainer)

• Docker Install documentation
• Docker Compose Install documentation

2. Download this compose.yaml (or use its content as a portainer stack)
3. adjust TZ and ACME_EMAIL to your values and maybe adjust other env options to your needs.
4. start NPMplus by running (or deploy your portainer stack)

docker compose up -d

5. Log in to the Admin UI When your docker container is running, connect to it on port 81 for the admin interface. Sometimes this can take a little bit because of the entropy of keys. You may need to open port 81 in your firewall. You may need to use another IP-Address. https://127.0.0.1:81 Default Admin User:

Email:    admin@example.org
Password: iArhP1j7p1P6TA92FA2FMbbUGYqwcYzxC4AVEe12Wbi94FY9gNN62aKyF1shrvG4NycjjX9KfmDQiwkLZH1ZDR9xMjiG2QmoHXi

Immediately after logging in with this default user you will be asked to modify your details and change your password.

Crowdsec

1. Install crowdsec using this compose file: https://github.com/ZoeyVid/NPMplus/blob/develop/compose.crowdsec.yaml and enable LOGROTATE in the NPMplus compose file
2. open /opt/crowdsec/conf/acquis.d/npmplus.yaml and fill it with:

filenames:
  - /opt/npm/nginx/access.log
labels:
  type: npmplus
---
source: docker
container_name:
 - npmplus
labels:
  type: npmplus
---
source: docker
container_name:
 - npmplus
labels:
  type: modsecurity
---
listen_addr: 0.0.0.0:7422
appsec_config: crowdsecurity/appsec-default
name: appsec
source: appsec
labels:
  type: appsec

3. make sure to use network_mode: host in your compose file
4. run docker exec crowdsec cscli bouncers add npmplus -o raw and save the output
5. open /opt/npm/etc/crowdsec/crowdsec.conf
6. set ENABLED to true
7. use the output of step 5 as API_KEY
8. save the file
9. set LOGROTATE to true in your compose.yaml
10. redeploy the compose.yaml

coreruleset plugins

1. Download the plugin (all files inside the plugins folder of the git repo), most time: <plugin-name>-before.conf, <plugin-name>-config.conf and <plugin-name>-after.conf and sometimes <plugin-name>.data and/or <plugin-name>.lua or somilar files
2. put them into the /opt/npm/etc/modsecurity/crs-plugins folder
3. maybe open the /opt/npm/etc/modsecurity/crs-plugins/<plugin-name>-config.conf and configure the plugin

Use as webserver

1. Create a new Proxy Host
2. Set Scheme to https, Forward Hostname / IP to 0.0.0.0, Forward Port to 1 and enable Websockets Support (you can also use other values, since these get fully ignored)
3. Maybe set an Access List
4. Make your TLS Settings

a) Custom Nginx Configuration (advanced tab), which looks the following for file server:

• Note: the slash at the end of the file path is important

location / {
    include conf.d/include/always.conf;
    alias /var/www/<your-html-site-folder-name>/;
    fancyindex off; # alternative to nginxs "index" option (looks better and has more options)
}

b) Custom Nginx Configuration (advanced tab), which looks the following for file server and php:

• Note: the slash at the end of the file path is important
• Note: first enable PHP82 and/or PHP83 inside your compose file
• Note: you can replace fastcgi_pass php82; with fastcgi_pass php83;
• Note: to add more php extension using envs you can set in the compose file

location / {
    include conf.d/include/always.conf;
    alias /var/www/<your-html-site-folder-name>/;
    fancyindex off; # alternative to nginxs "index" option (looks better and has more options)

    location ~ [^/]\.php(/|$) {
        fastcgi_pass php82;
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        if (!-f $document_root$fastcgi_script_name) {
            return 404;
        }
    }
}

prerun scripts (EXPERT option) - if you don't know what this is, ignore it

run order: entrypoint.sh (prerun scripts) => start.sh => launch.sh
if you need to run scripts before NPMplus launches put them under: /opt/npm/etc/prerun/*.sh (please add #!/bin/sh / #!/bin/bash to the top of the script)
you need to create this folder yourself - NOTE: I won't help you creating those patches/scripts if you need them you also need to know how to create them
