I have the following Situation:
I am running a Windows 8 Maschine with Sonic Wall Netextender on it (customer request ;-/). MY Network is secured thru TMG 2010. When I am inside my LAN I am not oble to connect to my customers Sonicwall with Netextender Client.
I have created a FW rule allowing TCP IP from internal to the specified IP, beside this I have created a Network rule from my internal Network to the customers Firewall IP (route).
When I try the Connection TMG tells me that
"A connection was closed because no SYN/ACK reply was received from the Server"
What is my fault ?
Thanks in advance !
