Can't access second network on Corporate network via VPN

[explosivo]

I have a vpn to our corporate network... Both NST5GT's

Home Network
192.168.3.0/24
//VPN TUNNEL\\
Corporate Network
10.178.5.0/24

Sub Network @ Corporate Site
10.178.50.0/24

How can I access this second network at our corporate site via my home network thru my VPN Tunnel. I have setup a route @ the corp network, I can ping any host on the 10.178.50.0 subnetwork....

I don't want to re-do my VPN policies, routes, etc.. to 10.178.0.0 /16. This worked but only for a while. I have also tried creating a routes at my netscreen but they didn't work.

Thanks!

Al little confused. You can ping all hosts on 10.178.50.0/24 subnet but not any hosts on 10.178.5.0/24 subnet? Is this correct? If so then what is the default gateway for hosts on 10.178.5.0/24 subnet? The Netscreen obviously has a route pointing to 192.168.3.0/24 subnet, but the hosts on 10.178.x.x also need to have a route to 192 subnet.
