How do I add routes for internal network in ISA server 2006

I'm trying to add more subnets to the internal network node in ISA server 2006. However, whenever I add an internal subnet (i'm using private ranges here) I get a configuration error saying that all traffic to or from the priate range I just added will be dropped as spoofed.

I think this is because ISA does not know how to route the traffice from the added subnets. Do I need to add static routes using the dos route commands or is there another place to edit routes in ISA server 2006?

yes - ISA uses the host operating system routing table so statics first as required followed by additions into the internal network LAT table in ISA
(configuration - networks - internal - properties - addresses)
