Wg0 can't start - Table does not exist (do you need to insmod?) Perhaps ip6tables or your kernel needs to be upgraded.

[DJIronic]

Describe the bug
I wanted to change an endpoint domain. I was unable to edit tge wg0, so I deleted in and created it again with the new domain on ednpoint. But now my wg0 server will not start.

To Reproduce
Steps to reproduce the behavior:
Add and remove a server and try to start it.

Platform:

• OS: Docker on Ubuntu 20.04.4 LTS
• Chrome with Adblock disabled
• I pulled the newst image today a part of debug process

Stacktrace/error output
Log form docker container when I click the start button:
wg-manager | b"[#] ip link add wg0 type wireguard\n[#] wg setconf wg0 /dev/fd/63\n[#] ip -4 address add 10.0.200.1/24 dev wg0\n[#] ip -6 address add fd42:42:42::1/64 dev wg0\n[#] ip link set mtu 1420 up dev wg0\n[#] iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE;ip6tables -A FORWARD -i wg0 -j ACCEPT; ip6tables -t nat -A POSTROUTING -o eth0 -j MASQUERADE;\nmodprobe: FATAL: Module ip6_tables not found in directory /lib/modules/5.4.0-104-generic\nip6tables v1.8.4 (legacy): can't initialize ip6tables table 'filter': Table does not exist (do you need to insmod?)\nPerhaps ip6tables or your kernel needs to be upgraded.\n[#] ip link delete dev wg0\n"

Additional context
I tried disabling IPv6, asi I dont have it on the server at all.

Screenshots

[outbackdingo]

just hit exactly the same error here

[outbackdingo]

root@vpn:~# sudo modprobe ip6_tables

and fixed!

[perara]

Perhaps thjis can be fixed with issuing modprobe from the docker if ip6_tables is not found.

after upgrading from ubuntu 23.04 to 23.10 i had exactly the same error,
switching back to 23.04 all works.

I paste the error in the log of the container
