stevenrix -> can't ping TMG in local network (16.Feb.2011 7:35:45 PM)
|
Hello;
I'm new to TMG firewall. I'm trying to install a 3-leg configuration but so far i haven't succeeded at all.
After installing TMG, I noticed i could not ping from any client. By default a firewall locks traffic so I went to firewall policy, clicked on tasks and chose in remote management to "enable this configuration group" for ICMP, and it still does not work: when I'm on a client with the IP of 192.168.0.108 and i try to ping the local lan of the TMG, there is no network connectivity (it does work from the TMG server to the internal and external network). My client is on the same subnet that the firewall in class C.
Am I missing something? I'm sure I do but i can't figure it out; any help would be appreciated, thank you in advance.
