UPDATE 1: It appears the problem is related to the Firewall with Hamachi. Is there a way to totally exclude filtering on a specific interface? I configured all to rules to be binded to the real interface and the Hamachi virtual nic is set to “Low Level Security” but I think we should have another option for “Disable Filtering on this Interface” (or kind of). Thanks!
The conflict between low level network software is quite possible. By default NeT Firewall intercepts all network adapters bound to TCP/IP and this can’t be change through the management console. It would require rebuilding NeT Firewall driver with a special check on Hamachi network interface.
I will check what really happens with Hamachi once I have some spare time.
