Port forwarding in a multihomed environment - 24.Aug.2006 3:42:29 AM

I am having trouble port forwarding to another server behind the ISA front end server. The network is as follows
:Adsl router (DMZ) to front end server (multihomed) -on server external interface is = 192.168.1.100 - internal interface(LAN) 10.0.0.X
: internal server on 10.0.0.x address behind the ISA server

i have no problems accessing the front end server using term services but cannot access the internal server using a different term services port #
i have setup RDP (terminal services) to the internal server on port 3390 (reg changed)
i have created a protocol definition and then created the server publishing rule

Is the problem that the external interface is a internal address (192.168.1.X) and ISA cannot route to the 10.0.0.x network

The local address table (LAT) only specifies the 10.0.0.x private network.... should i include the 192.168.1.X network as well or is this deemed not appropriate as it acts as the external interface behind the DMZ

Im a little lost please help..if you require anymore information please let me know
