Network within network issue - 5.Sep.2007 6:31:55 AM

Hi all,

Pls see attached pdf file for my network setup. Basically, there are two network segments, connected with routers. All the required routes have been added in Front end firewall and ISA Server.

After adding the required routes and before enable the ISA Firewall, all the workstations from both segments are able to browse internet, workstations from segment 192.168.2.0 able to access servers located in segment 192.168.1.0.

But, after enable the ISA firewall, workstations form segment B not able to browse internet, accessing any servers in segment 192.168.1.0. I did a test on workstation B; from this workstation, I able ping any IP from 192.168.1.0 segment and as well as Internet IP.

Both segments are defined in "Internal" Network. Should I define the subnet 1.0 and 2.0, and explicitly allow traffic between these 2 subnets?

My intention is to setup ISA as webproxy server, with all the clients configured as securenat and webproxy clients.

Any suggestion is welcome.

Hi,
have you added all the static routes in isa server?
Isa is not able to redirect the traffic, like a router.
if you try to ping from the isa server you can reach all the workstations in both branches?
