Two gateways in my home LAN

Hi,

I've have setup a LAN home using a DSL Router and it works fine using
192.168.1.1 as default gateway. In this LAN I've added a machine and
installed a VPN client to connect to my office. The idea was that this
machine should work as a second gateway for traffice to work but the VPN
software modifies the routing table and forces the default gateway to the
VPN gateway.

This is the routing table after I connect

What I wan't is a windows box in my network (192.168.1.103) that had a VPN
connection to my office and work as a second gateway for all traffic to
172.19.XX.

I have a couple of questions.

1. Can I run a post connect script to alter the routing table (the VPN
software keeps chaning it)
2. Do I need two network cards in the VPN gateway machine?
3 How do I route traffice from for instance 192.168.1.103 to 172.19.143.53
on the VPN machine ? Changing the routing table, bridging ?

Any help here would be great ?

Thanks,

If this is the microsoft VPN client all you need to to is open the
Properties of the VPN connection. Next Click on the Networking Tab.
Open the TCP/IP Properties. Click on Advanced. On the general Tap
uncheck the box "Use default gateway on remote computer. Save your
settings.
 
No this is a Shiva VPN client. I've been investigating this further and it
seems like the VPN client overwrites any changes to the routing table if I
manually edit it. I guess this is a dead end then...

no experience with the Shiva client, but have been able to accomplish
what you are looking for with Aventail, Microsoft, and Cisco so I
wouldn't give up.

Good Luck
