How to specify port number in compose file that is behind vpn container

Hi there!

I'm trying to set up two services (through docker) both of which use port 8080 by default. However I am wanting these to services to sit behind a VPN using Gluetun. I added both of the ports I want to use to the compose file, but this just leads to only one of the services working as the other one will say "port already in use". How can I strictly tell these services what port they shall use in the compose file?

This is how I did it so far;

docker-compose.yml ```yml

version: '3' services: vpn: image: qmcgaw/gluetun:latest container_name: vpn restart: unless-stopped cap_add: - NET_ADMIN environment: - VPN_SERVICE_PROVIDER=custom - VPN_TYPE=wireguard - VPN_ENDPOINT_IP=#### - VPN_ENDPOINT_PORT=#### - WIREGUARD_PUBLIC_KEY=#### - WIREGUARD_PRIVATE_KEY=#### - WIREGUARD_PRESHARED_KEY=#### - WIREGUARD_ADDRESSES=#### devices: - /dev/net/tun:/dev/net/tun ports: - '8080:8080' #VPN - 8888:8888/tcp - 8388:8388/tcp - 8388:8388/udp - 8000:8000/tcp - 8584:8584 - 8585:8585 volumes: - /docker/appdata/gluetun:/gluetun sabnzbd: image: lscr.io/linuxserver/sabnzbd:latest container_name: sabnzbd network_mode: container:vpn volumes: - /docker/appdata/sabnzbd/data:/config restart: unless-stopped qbittorrent:
container_name: qbittorrent
image: linuxserver/qbittorrent:latest restart: unless-stopped network_mode: container:vpn
volumes:
- /docker/appdata/qbitorrent:/config
```
