I need to connect an additional IP subnet to an existing Windows Essential Business Server 2008 network:
Internet -- Firewall Appliance -- EBS Security Server -- internal network (192.168.254.0/24) -- Router Appliance -- 2nd internal network appliance (192.168.251.0/24)
I installed the router, I added the route to TMG on the security server via the "getting started wizard". A "route print" command shows the new route:
Network Address Netmask Gateway Address Metric
192.168.251.0 255.255.255.0 192.168.254.254 256
0.0.0.0 0.0.0.0 192.168.250.1 1
However, I can't access systems located on the additional subnet. Pinging systems does not work. I need to add the route locally on a computer to be able to ping systems located on the other side of the router. Looks like I am having some ICMP Redirect issue. Do I need to add a TMG rule for this to work ?
Any help would be appreciated.
