Have you built and installed libxt_WGOBFS.so?

from xt_wgobfs.

marek22k commented on September 4, 2024

Yes, I have.

$ ls /lib/modules/5.10.0-18-amd64/kernel/net/netfilter/ | grep xt_WG
xt_WGOBFS.ko

from xt_wgobfs.

That is the kernel module. You also need userland. See readme.

Userland?
I only see

Run make in kernel/ to build kernel module. Copy xt_WGOBFS.ko to /lib/modules/yourkernelversion/kernel/net/netfilter/, then run depmod -a.

Run make in xtables/ to build iptables extension. Copy libxt_WGOBFS.so to xtables directory.

and I did both.

Somehow Debian 11 does not load the kernel module automatically. Need modprobe xt_WGOBFS. See updated readme.
