VPN behind iptables v1.2.2

9 Sep 2001

      Hi list,

i have a VPN Gateway behind a linux iptables Firewall with v 1.2.2. But
the iptables rules are not be able to allow or drop the GRE protocol
(number 47). How can i configure the iptables to allow this protocol? If
i allow only tcp or udp, the signing up to the Gateway don't work.

Thanx for help
