Hi
I have an ISA 2000 installed on a windows 2000 server
i have another branch connected to my local lan by routers i have the subnet 192.168.0.X
and the branch has the subnet 192.168.1.X
the routers are configured so the clients in the branch office can access my internal servers
i want to give internet access to the branch users from my ISA server
i created a LAT entry with their subnet and created an Access rule for them
I installed firewall client on the pcs in the branch office but i couldnt detect my ISA server or even ping it
how can i give access to the branch office to access the internet from the ISA server
PS the router that connects the two branches are connected directly to my lan
regards
J0hnny

Your windows 200 server cant have 2 default gateways so Id expect only your external "internet side" network card has a default gateway setting.
As such, your internal network card in the ISA box literally doesn't know HOW t get to your other internal branch network sites.

See step 6 of http://technet.microsoft.com/en-us/library/cc778535.aspx
basically if your local WAN (Wide Area Network) internal router is the IP address 192.168.0.254 and your other branch uses 192.168.1.X then use this command on your ISA server machine
route add -p 192.168.1.0 mask 255.255.255.0 192.168.0.254

easy
