Portforwarding

I want to make a VPN-connection between my homeadress and my work. I have
bought 2 Linksys gateway's allready and configured them. The connection
works right between the two gateway's. But then I have to make a connection
with my NT-server, but between the server and the Linksys gateway is an
Linux-server (Debian) installed. This Linux-server blocks the VPN-connection
because certain ports are closed (TCP 1723 en UDP 500). I don't know how it
works, I don't know anything about Linux yet. I have read something about
portforwarding, but what kind of statements and where I can do this, I have'nt
found. Who can help me with this. Network and it's IP-adresses:

Home Linksys 192.168.2.253

Work Linksys 192.168.1.253

Linux Nic in: 192.168.1.76

Nic out: 172.10.10.252

Server 172.10.10.1

i'm not sure if you can port forward a VPN connection, at least a
windows VPN. if you are encapsulating an IPsec connection within UDP
then it *might* be possible. but i'm not sure if you can forward a GRE
or ESP tunnel, it's not a port but a protocol.

you might have to forward *all* traffic instead of port forwarding.
