Hi,

We have a current network as attached, running Windows 2003 Server, Exchange, SQL and ISA 2004, we do not want to use the ISA for VPN, but 2 Watchgaurd VPN Boxes, I have setup the Watchguards witha VPN tunnel between the two sites, but the ISA Complains about the 192.168.8.0 network, could you please guide me or point me in the right direction, to setup the ISA to except the 192.168.8.0 Network and allow me to acces the resources on the 172.16.8.0 Network.

Your ISA and the watchguard have external access at site A.  You need to define a route on the ISA for traffic destined to 192.168.8.0 255.255.255.0 to be sent through the watchguard device. i.e. you define the gateway for the 192.168.8.0 255.255.255.0 network to be 172.16.8.10.  You would also need to define the 192.168.8.0 255.255.255.0 as "trusted" on the ISA or setup specific rules to allow 192.168.8.x IPs to access whatever resources you want to allow the remote workstations to access.
