Ts3init Linux netfilter module

ts3init module cant be compiled on 5+ kernel, xtables has to many changes in API i tried to rewrite but its too much for me

this issue is since Kernel Version =>4.10 i hope that will be updated as soon as possible

Dave means here is the technical support but i don’t found this.

The ts3init_linux_netfilter_module on Github ( https://github.com/TeamSpeak-Systems/ts3init_linux_netfilter_module#ts3init-linux-netfilter-module ) isn’t working with Debian 10 and Linux_kernel_headers =>4.19 . Can you fix this please. i will use it and it’s absolutly fantastic. Please update this for the newest Debian.

Thx for this but i think a answer is better as merge. fix this. Since >1 year this problem isn’t solved

The attacks on the voice port have increased a lot in the last weeks. The TeamSpeak Server is 100% busy, packet loss and a connection loss is the result even if the host itself and all other services remains reachable. Unfortunately the voice packets are not transmitted over TCP so I wanted to try this filter.

I can confirm the issue with Debian 10 and an up-to-date 4.19 kernel:

On a test environment with kernel 4.9 everything is ok but this is not an option for me. I also hope for an update soon.
