Help with selfhosted wireguard routed through gluetun

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"
