[SOLVED] How can I get WinBoat to use Docker's default network bridge "docker0"

[GaryScottMartin]

I am trying to run WinBoat on an ArchLinux system with nftables and iptables-nft installed. Docker containers other than WinBoat use the 172.17.0.0/16 subnet and all have network connectivity. WinBoat is using the 172.30.0.0/16 subnet and has no network connectivity. I had to add firewall rules to my /etc/nftables.conf file to allow docker0 traffic. I believe that I could get network connectivity to WinBoat I could force it to use the default Docker bridge or if I knew the name it assigns to its network config. Has anybody gotten network connectivity using nftables/iptable-nft? The only thing I uncovered in multiple web searches was one guy who gave up trying to get WinBoat to work with nftables a year ago.

For anyone with this issue, I was able to get connectivity by network_mode: bridge to the Windows service in docker-compose.yml just above the ports: line:

name: "winboat"
volumes:
  data: 
services:
  windows:
    image: "ghcr.io/dockur/windows:5.07"
    container_name: "WinBoat"
    environment:
      VERSION: "custom"
      RAM_SIZE: "12G"
      CPU_CORES: "8"
      DISK_SIZE: "512G"
      USERNAME: "****"
      PASSWORD: "********"
      HOME: "${HOME}"
      LANGUAGE: "English"
      HOST_PORTS: "7149"
      ARGUMENTS: "-qmp tcp:0.0.0.0:7149,server,wait=off"
    cap_add:
      - "NET_ADMIN"
    privileged: true
    network_mode: bridge
    ports:
      - "8006:8006"
      - "7148:7148"
      - "7149:7149"
      - "3389:3389/tcp"
      - "3389:3389/udp"
    stop_grace_period: "120s"
    restart: "on-failure"
    volumes:
      - "/home/gary/Applications/winboat:/storage"
      - "/dev/bus/usb:/dev/bus/usb"
      - "./oem:/oem"
      - "/wdata/Users/GaryS/Documents/Computing/Operating Systems/Windows 11/Win11_25H2_English_x64.iso:/boot.iso"
    devices:
      - "/dev/kvm"

It still shows the IP address as 172.30.0.2 and the default gateway at 172.30.0.1, but I do have internet connectivity without any additional modifications to my nftables.conf file.
