Pritunl container built on Alpine Linux. Supports IPv6 and running behind a reverse proxy. This container requires an external Mongo DB and should be run via Docker Compose or other orchestration.

This container exposes the following five ports:

• 80/tcp pritunl web server http port (standalone mode)
• 443/tcp pritunl web server https port (standalone and wireguard reverse-proxy mode)
• 1194/tcp pritunl VPN service port
• 1194/tcp pritunl OpenVPN service port
• 1195/udp pritunl wireguard service port - No default in app, this is a suggestion only.
• 9700/tcp pritunl web server http port (non-wireguard reverse-proxy mode)

Wireguard

The Docker host is required to have wireguard kernel modules installed and loaded.

Wireguard also requires that the pritunl web service exists internally on port 443 with SSL enabled (self-signed or LetsEncrypt cert). Without this clients will fail to connect or connection will time out after 15s in wireguard mode. This presents problems with existing reverse-proxy support using port 9700 and no SSL.

Wireguard + Traefik 1.X reverse-proxy + pritunl SSL self-signed cert:

• SetInsecureSkipVerify = true in Traefik 1.Xtraefik.toml config file (configure Traefik to accept invalid/self-signed certs)
• Set container ENV variableREVERSE_PROXY=true (configure pritunl for reverse-proxy/load-balance mode)
• Set container ENV variableWIREGUARD=true (configure pritunl to run web interface on port 443 with SSL)

Further pritunl wireguard information available at:

OpenVPN server fails to start, insmod error

ip6tables v1.8.3 (legacy): can't initialize ip6tables table 'filter': Table does not exist (do you need to insmod?) is repeatedly logged in the Docker container log along with python errors.

Load the ip6tables_filter kernel module on your Docker host and restart the container:

user@host:~$ sudo modprobe ip6table_filteruser@host:~$ sudo docker restart pritunl

This may need to be performed after kernel upgrades and reboots on the Docker host.
