iptables-restore: unable to initialize table 'raw'

[mazzy89]

Describe the bug

I've updated nordlynx container to the recent version. It was a while I was not update it. I believe for more than 6 month.

Now the interface does not come anymore up and I get the error:

iptables-restore v1.8.7 (legacy): iptables-restore: unable to initialize table 'raw'

To Reproduce using docker CLI

I'm using Podman so it's not relevant.

To Reproduce using docker-compose

I'm using Podman so it's not relevant.

Expected behavior

I would expect that the container would come up.

It says connected but the container does not have a connection to the internet and wg show does not reveal any interface.

Additional context

It's running on UDM-PRO-SE as a podman container. It worked before the recent releases. The wireguard kernel and tools versions are

WireGuard Module Version: 1.0.20211208
WireGuard Tools Version: 1.0.20210914

As suggested I've tried what recommended here linuxserver#42 (comment) but w/o luck.

[mazzy89]

So according to this linuxserver#138 (comment), I would need the iptables_raw kernel module but UDM Pro SE does not have it and it is not possible to load it anymore.

[mazzy89]

I've fixed this by loding the kernel modules from here https://github.com/tusc/wireguard-kmod/blob/main/src/wireguard/setup_wireguard.sh#L63

Now it works. Closing.
