Hi
Had a look and there are a couple of errors in the code. It’s
looking for the libipq.h in a different directory and it’s
referencing sys/types.h which should be linux/types.h.
You need to add the #include between netinit and the netfilter one
which exist in the code;
Also because the way the install script runs you need to rebuild the
edited one so it unpacks the modified code.
