Dear Hi,
I am using TMG configure on edge firewall and client are connected with TMG IP address in default gateway and TMG server is also join with domain. The problem is that I am configure simple firewall rule to access internet from local to external after applying this changes internet working but after few minutes not working without applying no more changes and google chrome show error ERR_Connection_Timed_Out but only MSN.com open. I cann't understand what's the problem.
