linux firewall configuration to support Nortel Contivity client

linux firewall configuration to support Nortel Contivity client

[Michael]

Hi,

At home I have a linux box (2.6.11.11 kernel) acting as my gateway. It
is running nat, upnpd & iproute2 all quite happily.

What I want to do next is make the vpn client (Nortel Contivity) on my
work laptop play nicely. I've been looking at the ip_nat_pptp &
ip_nat_proto_gre patches from patch-o-matic.

I'm not sure what kind of tunel Contivity tries to establish (or much
else about it works) Has anybody out there setup something similiar to
this? Or know much about Contivity sets up a vpn?

Michael you may want to try sniffing the traffic that your notebook gives off when it has it's ""VPN up and running.  If the traffic is IP/ESP (IP protocol 50) then the traffic is an IPSec tunnel.  If the traffic is IP/GRE (IP protocol 47) then the tunnel is a GRE tunnel.
