Hi at all the list
I got the latest (5.3) free-bsd edition and need to know if  there's support for gre protocol into multiple connections
We got many clients for vpn into the office acessing a remote server and passing through the firewall who has two interfaces(one public and one internal)
 in a round-trip way meaning that the packet has to do natd in the go and in the back way to access the  10.x.x.x internal network
I'm a little worried because we used debian with the kernel 2.4.26 and iptables 1.2.11 and needed to do  many adjusts and recompiles until it came to work finally.....with 
the patch-o-matic added.
So the question is if in free-bsd and the related ipfw is the same headache....
Of course i'm a newbie hehehe....
May you have a look at this problem i'd be grateful...
thanks very very much
