Dear All,

I have 2 sites the first one is the HQ the second one is the Branch and it is connected to each other with a VPN connection through one of the ISP's I have domain controller , ISA server, Exchange server, installed on the HQ and I am trying to make the Branch browse the internet over the HQ ISA server.

The Network ip range for the HQ is 192.168.100.* "Taken by DHCP on the domain controller".
The Network IP range for the Branch is 192.168.101.* "I configured the router to give this range to the connected computers.

I have a gateway for both on the routers 192.168.100.254 and 192.168.101.254.

I gave the computers on each location its internal gateway but actually I have 2 problems:

1- The people on the Branch are not able to browse the internet connection though the ISA server of the HQ but on the same time they are able to browse the computers in the HQ and other servers but they can not brows the ISA or access it or even the ISA Firewall client can not connect to the ISA server and the HQ people are smoothly using the internet without any problems or special configurations.
2- I need to publish my Exchange server to give it the real IP to pass from the ISA, but I don't know where to add the real IP's to the ISA firewall IP's list.

What gateway address are you using on the PC's at Branch?
