iptables Error

[mikeleord]

Hello,
via portainer I used this Docker Compose:

version: "3"
services:
  windows:
    image: dockurr/windows
    container_name: windows
    devices:
      - /dev/kvm
    cap_add:
      - NET_ADMIN
    ports:
      - 8006:8006
      - 3389:3389/tcp
      - 3389:3389/udp
    stop_grace_period: 2m
    restart: on-failure
    environment:
      VERSION: "win10"
      RAM_SIZE: "4G"
      CPU_CORES: "2"
      DISK_SIZE: "32G"
      MANUAL: "Y"
    volumes:
      - /docker/win:/storage

but i get this error:

iptables v1.8.10 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
❯ ERROR: Status 3 while: iptables -t nat -A POSTROUTING -o "$VM_NET_DEV" -j MASQUERADE (line 178/301)
❯ Starting Windows for Docker v2.04...
❯ For support visit https://github.com/dockur/windows

what can I verify?
Thank you

sudo modprobe ip_tables
sudo modprobe iptable_nat

Should work.

If you don't need network access in the machine, for example you just need to test some Windows app, you can now also disable the network in the latest version (v2.06):

environment:
  NETWORK: "N"

That will also work around that the iptables error.
