For Lync reverse proxy on our TMG server we have a secondary IP address (192.168.100.150) added to the external adapter, then a NAT rule from our firewall to go to this IP.
from the TMG server i cant ping this secondary address, even though I can ping all of the other addresses on this adapter.
I think its something to do with a static route, when i looked it had a static for 192.168.168.100.150 to go to 192.168.100.1 (default gateway) with a metric of 256 subnet mask of 255.255.255.255
I can ping the DG but just not this .150 address. i removed the route and still no change, because of this the reverse proxy isnt working, any ideas whether there should or shouldnt be a static route added for this network adapter?
