Hi there,

I wish to run a wireguard docker through a glueton docker so that i can access my paid vpn from my own server. This is what i want:

client -> wireguard docker(selfhosted) -> gluetun docker(connected to paid VPN) -> internet

I have posted before with this issue but still cannot get it to work as expected. I am not sure if there is issues with the wireguard docker not being able to route back through from gluetun as it is trying to force traffic through the tunnel.

Any help would be much appreciated.

docker-compose.yml:

services:
  gluetun_test:
    image: qmcgaw/gluetun
    container_name: gluetun_test
    cap_add:
      - NET_ADMIN
    ports:
      - "5010:5000"
      - "5011:8000"
     # Port of the WireGuard VPN server
      - "36843:36843/udp"
    environment:
      - VPN_SERVICE_PROVIDER=custom
      - VPN_TYPE=wireguard
      - WIREGUARD_PUBLIC_KEY=

      - VPN_ENDPOINT_IP=ip
      - VPN_ENDPOINT_PORT=port
      - WIREGUARD_ADDRESSES="10.2.0.2/32"

  wireguard:

I have a paid external vpn(Nordvpn using gluetun) and am currently hosting my own wireguard vpn on my server through docker. is there a way to get the traffic from my selfhosted vpn to tunnel through my paid vpn? This is my docker-compose file atm.

services:
  gluetun_test:
    image: qmcgaw/gluetun
    container_name: gluetun_test
    cap_add:
      - NET_ADMIN
    ports:
      - "5010:5000"
      # Port of the WireGuard VPN server
      - "36843:36843/udp"
    environment:
      - VPN_SERVICE_PROVIDER=nordvpn
      - VPN_TYPE=wireguard
      - WIREGUARD_PRIVATE_KEY=redacted
      - SERVER_COUNTRIES=United Kingdom

  wireguard:
    image: linuxserver/wireguard:latest
    container_name: wireguard
    cap_add:
      - NET_ADMIN
    environment:
      - PUID=1000
      - PGID=1000
    volumes:
      - ./wireguard/config:/config
#    ports:
      # Port for WireGuard-UI
#      - "5010:5000"
      # Port of the WireGuard VPN server
#      - "36843:36843/udp"
    network_mode: service:gluetun_test
