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

wg0.conf

[Interface]
Address = 10.252.1.0/24
ListenPort = 36843
PrivateKey = redacted
MTU = 1450
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
Table =

Any help would be great! Thanks!

    ip rule add from WG-NET table TABLE
ip route add default via GLUETUN-GW dev GLUETUN-DEV src GLUETUN-IP table TABLE
ip route add WG-NET dev WG-DEV src WG-IP

    First one causes all packets coming from wireguard network to use the routing table TABLE, second one sets the default gateway in that table to gluetun, third one sets up routing back to the wireguard network (this one probably already exists)

    Where

    • TABLE: A routing table name, mapped in /etc/iproute2/rt_tables
    • GLUETUN-GW: The gateway IP of the gluetun tunnel, e.g. 10.128.1.1
    • GLUETUN-DEV: The gluetun tunnel netdev, e.g. tap0
    • GLUETUN-IP: The gluetun tunnel device’s IP (your machine), e.g. 10.128.1.2
    • WG-NET: your wireguard network, e.g. 10.100.0.0/24
    • WG-DEV: The wireguard network device, e.g. wg0
    • WG-IP: The wireguard network device’s IP (your machine), e.g. 10.100.0.1

    Untested, so not sure if it works.
