Passing ppp/vpn with ip-filter

[Erik Norgaard]

Hi:

I have the following setup:

   XP -- FBSD -- Ineternet --- Work

I need to setup a VPN connection from my work station to work but the 
connection failes, presumably blocked by my firewall. The FBSD gateway 
use ip filter to filter traffic with a default block. Listening on the 
pflog inteface I got this:

1. 051533 rule 97/0(match): block in on vr1: 172.16.0.127 > 217.126.X.X: 
GREv1, call 62316, seq 9, proto PPP (0x880b), length 37: [|ppp]

How do I create a rule to pass this connection?

Thanks, Erik
