Connect to a client server through company VPN

Connect to a client server through company VPN

I'm trying to connect to a client's server which is fire-walled to only be
connectable via my companies IP address.
I'm using Shrew soft VPN on windows and have access to connect to my
companies network via VPN. The vpn is setup to only route internal
requests through the VPN, and all other things through my home network.
Things I've tired:
route add 107.xxx.xxx.xxx mask 255.255.255.255 0.0.0.0 if 16
route add 107.xxx.xxx.xxx mask 255.255.255.255 192.168.5.1 if 16
Neither of which seem to work.
My home subnet is 192.168.5.0/24
if 16 is the shrew soft vpn interface
107.xxx.xxx.xxx is the server I need to connect to through the VPN
The VPN assigned subnet for my connection is 192.168.200.0/24
From what I've read the top route that I added should do the trick, but I
guess I'm missing something.
Thanks in advance!
