Windows server 2003.
MS TMG with two NICs.

I have two vlans in my network.
vlan1: 200.1.1.0/255.255.255.0
vlan2: 200.1.2.0/255.255.255.0

I have an ISA server with two NICs in vlan2.

NIC1: 200.1.2.100 (default gateway set to nothing - if I set this to 200.1.2.1 then I can ping to vlan1 machines but cant proxy for internet i.e. more than 1 default gateway issue)

NIC2: 125.1.1.125 (default gateway set to 125.1.1.1)
Router IP: 125.1.1.1

I am unable to ping to any IP in vlan1 from this server(200.1.2.100) or from vlan1 to this server(200.1.2.100). I get a "Destination host unreachable" message.

Perhaps I am able to ping from vlan1 to vlan2 (or vice versa) with other machines that have one NIC installed.

Here is my route print status of 200 and 0.
Root Print

What static route should I add? if any, or what other work around are possible?

  • have you tried this yes? http://lmgtfy.com/?q=isa+server+routing – Sum1sAdmin Apr 26 '16 at 09:42
  • Yes and tried to add different routes but no idea where am making mistake, actually not a core network guy. – Rafi Apr 26 '16 at 09:51
  • the ISA server is a proxy server for outbound internet access, it sits at the edge of your network - usually all vlans are configured to proxy out via ISA but the inter VLAN routing should happen inside the network and not at its' perimeter - so you need to configure your layer 3 switch.. what is the default for your clients? a VLAN gateway or the ISA? – Sum1sAdmin Apr 26 '16 at 10:32
  • I am able to ping other single NIC machines of vlan1 to vlan2 or vice versa. Hence switches are configured properly. My only concern is to send a ping between the vlans and not to proxy for internet. I have mentioned ISA in my question to explain the server details only. – Rafi Apr 27 '16 at 04:52
  • Any chances to get a solution here? – Rafi Jun 06 '16 at 05:40
