[TriLUG] RedHat 8.0 / IPTables / GRE packets?

[Jon Carnes]

My guess is that you need something compiled into your kernel in order
for it to handle GRE properly (or even at all).  I've always had
problems with Red Hat and GRE so I stopped using Red Hat on any server
that needed GRE or IPSec.  I use Mandrake Linux or OpenBSD and am a much
happier camper.
