This message is really for xtang, since he maintans the port. 
If anyone else need IPFilter 3.6.28 or newer ported to 6.2 NC please let him know.
This is the only program that is holding me back from upgrading to 6.2.
It isn’t really a “port” per-se.
The new BSD stack used in the PE/SE installs of Neutrino has a different interface for hooking in the filtering. It would be more interesting to see why your setup was getting balled up on 6.2.
