Wireguard on QNAP

[nickvin]

Having an issue on QNAP TS-451+ FW:5.0.0.1986 trying to run the container with Wireguard. Openvpn works fine.

2022-04-05 20:09:25,270 DEBG 'start-script' stderr output:
iptables-restore v1.8.7 (legacy): iptables-restore: unable to initialize table 'raw'

Error occurred at line: 1
Try `iptables-restore -h' or 'iptables-restore --help' for more information.

Not sure if this problem is related, but a similar issue was raised for the linuxserver/docker-wireguard container: https://github.com/linuxserver/docker-wireguard/issues/42

I'm running the following docker-compose, but tried many iterations without any success:

version: "3.8"

    qbittorrent:
        container_name: qbittorrent
        image: binhex/arch-qbittorrentvpn

I ran into this, and fixed it with the suggestion here https://github.com/linuxserver/docker-wireguard/issues/42#issuecomment-888930759 (a specific comment from the link you referenced).

Essentially it's complaining about 0.0.0.0/0.

Still haven't fully gotten WireGuard to work (running into other problems) but hopefully this is still helpful.

AllowedIPs is being overwritten on container start to AllowedIPs = 0.0.0.0/0 so changing that setting has no effect 🤔

[KosherBacon]

It sounds like you might be using PIA. If you're okay with losing port forwarding, you can generate the file, edit it to AllowedIPs = 0.0.0.0/1, 128.0.0.0/1 and change VPN_PROV to custom. Upon restart it shouldn't overwrite the change (at least it didn't for me).

@KosherBacon Have you completed your wireguard setup on qnap? Everything seems connected on my side. But I dont seem to have access to anything.. no VPN, no ping to any IPs etc. Completely blocked. wg show does not display latest handshake info :(

[root@c5826c6b934f /]# wg show
interface: wg0
  public key: QvxxxxxxxxxxxxxxxxxxxxxxzgCicGXjWR4=
  private key: (hidden)
  listening port: 46906

peer: UrQiI9ISdPPzd4ARw1NHOPKKvKvxUhjwRjaI0JpJFgM=
  endpoint: 193.32.249.66:51820
  allowed ips: 0.0.0.0/1, 128.0.0.0/1
  transfer: 0 B received, 16.19 KiB sent

btw, the same wg0.conf works in the QNAP host (not inside docker)

any idea?

[SteadBytes]

@KosherBacon sorry for the slow reply! Thank you for the suggestion, but I'm using Mullvad not PIA so already had AllowedIPs=0.0.0.0/1, 128.0.0.0/1 and VPN_PROV=custom. It's interesting that yours isn't getting overwritten 🤔

[KosherBacon]

@ahurtaud I have unfortunately not gotten it to work.

WireGuard will "start" but won't complete a handshake. I just see RX as 0 bytes indefinitely, same as you.

ok thanks for the info, on my side I left the binhex image and went to the native qbittorent with bind network interface on the host.. :/
