gluetun port forwarding issue

[cubesmi 0]

Hi!

I'm struggling with gluetun port forwarding to another container.

In order to debug my setup I came up with following docker compose which sets up a simple nginx webserver and VPN port forwarding.

• 'wget localhost:80' from inside the gluetun container works
• 'wget <host-ip>:29099' from LAN works as well, if I expose 29099:80 in the gluetun container

Can anyone spot the flaw in following setup? Thanks in advance 🙂

version: "3"
services:
  gluetun-v1:
    image: qmcgaw/gluetun:v3.33
    container_name: gluetun-v1
    cap_add:
      - NET_ADMIN
    environment:
      - VPN_SERVICE_PROVIDER=airvpn
      - VPN_TYPE=wireguard
      - WIREGUARD_PRIVATE_KEY=xxx
      - WIREGUARD_PRESHARED_KEY=xxx
      - WIREGUARD_ADDRESSES=10.147.182.65/32
      - SERVER_REGIONS=Europe
      - FIREWALL_VPN_INPUT_PORTS=29099
  nginx:
    image: nginx
    container_name: nginx-v1
    network_mode: service:gluetun-v1

Cheers, cubesmi

Please describe your own issue, what you've tried and where you're stuck. Your setup is different and might have a different core issue than the one you refer to.

I just set up airvpn with gluetun today. I was using Mullvad previously and have always had the ports defined in the container. You probably need to add this to the gluetun container's compose:
 

    ports:
      - 29099:80
      - 29099:80/udp

You change the port on the VPN server side from 29099 to 80, which is then forwarded to your server with docker running on.
I would assume the correct environment variable setting would be FIREWALL_VPN_INPUT_PORTS=80 as the traffic arrives at port 80 at your machine.

This exposes the web server port through the gluetun container on the host machine, unfortunately this doesn't solve the issue; the web server is still not accessible via the public airvpn ip address 😞

Hey - has anybody figured this out yet? I'd like to get this set up as well.

Did anyone solve this yet? I have the exact same setup issue with Nginx and Gluetun. Works fine locally but can't get it to work remotely
