The ReverseProxy is reachable under 192.168.88.3 which is located in the ServerVLAN.

Every incoming packages from outside are forwarded to this IP.

The ReverseProxy also forces outside connections to use HTTPS/SSL and will provide a SSL-Certificate.

Basic Setup

Nginx Proxy Manager

Download installation script and run it

wget --no-cache -qO - https://raw.githubusercontent.com/ej52/proxmox/main/lxc/nginx-proxy-manager/setup.sh | sh

After installation, the webinterface should be reachable, standard login is

Email:    admin@example.com

Update

Update NPM with following command

wget --no-cache -qO - https://raw.githubusercontent.com/ej52/proxmox/main/lxc/nginx-proxy-manager/setup.sh | sh

Authelia

For security reasons and convenience, the login portal Authelia will be installed.

Redis-Server

Install Redis with the following command:

apt install redis-server

After installing Redis, start redis service and enable it to start after system reboot with the following command:

systemctl start redis-server
systemctl enable redis-server

Verify the status of the redis server:

By default, Redis listening on the localhost on port 6379. You can check it with the following command:

ps -ef | grep redis

Open Redis Config and set passphrase for redis server, which is needed in the authelia configuration file. Find # requirepass in line 790 and change it requirepass "my_redis_password"

nano /etc/redis/redis.conf

Restart redis to apply config

systemctl restart redis

Test if passphrase is working correctly and exit

redis-cli
AUTH yourpassword
exit

Installation

Download and install package file:

wget https://github.com/authelia/authelia/releases/download/v4.36.3/authelia_v4.36.3_amd64.deb
apt install ./authelia_v4.36.3_amd64.deb

configuration.yml

Edit onfiguration file, modify and paste configuration.yml

nano /etc/authelia/configuration.yml

Restrict permissions for the configuration file

chmod 0600 /etc/authelia/configuration.yml

users_database.yml

Create users_database, modify and paste users_database.yml

nano /etc/authelia/users_database.yml

Password hash can be generated with following command

/usr/bin/authelia hash-password 'yourpassword' -i1 -k32 -l16 -m256 -p8

Restrict permissions for the users_database

chmod 0600 /etc/authelia/users_database.yml

Start authelia and check status

systemctl start authelia
systemctl status authelia

Enable authelia at boot

systemctl enable authelia

Update

To update authelia, I made an bash script: UpdateAuthelia.sh

Configure Nginx Proxy Manager

Create Proxy-Host for Authelia:

  • auth.flowerhouse.at -> Scheme: http, Forward IP: 192.168.88.3, Port: 9091
  • Chache Assests: On, Block Common Exploits: On
  • At the advanced tab add content of file authelia_portal.conf

To enable the login portal for a host, go to the advanced tab and add the contenct of protected_endpoint.conf

  • Line 3, 33 and 34 needs to be edited
