Allowing GRE in IPFILTER

[Calvin Lane]

Hello everyone,

I've recently installed and configured mpd. I've been able to establish VPN 
connections with no problem internally on my network. When I attempt to 
establish a connection through my firewall, I get a number of error 
messages. The problem is that I'm not allowing GRE to get through on my 
firewall. Here is currently what I have:

pass in quick on xl0 proto gre from any to
192.168.10.253/24<http://192.168.10.253/24>
pass out quick on xl0 proto gre from
192.168.10.253/24<http://192.168.10.253/24>to any

Please let me know what the correct syntax is for allowing gre traffic 
through through an ipfilter firewall running BSD 4.10. Thanks.
