VPN client behind Debian Linux router

Hey there,

I have set up a Debian Linux box to act as my router (to replace a
Linksys router.) I have everything working great (NAT, etc.) but I
forgot that I use a VPN connection on a Windows XP box to connect to a
remote network (which is running a VPN server on NT4, I believe.

So my question is how do I allow my firewall to allow my VPN client to
access this remote network (I am not interested in setting up a VPN
server, just in getting my Windows box with the VPN connection to
connect to the remote network.)

Any help would be appreciated.

I suspect your are connectiong to your NT4 server using the PPTP VPN
protocol :

- your firewall must allow the GRE protocol to pass throw
/sbin/iptables -A INPUT -p gre -j ACCEPT

More information on the PPTP protocol :
