Hello,
according to Firewall settings, I have to create a rule to allow remote IP address to reach the machine. The rule for "All Apps + Any Network" works fine but I want to restrict the access to a specific remote IP address. Once I set it in Custom Remote Address, the incoming connection stop working. If I understood correctly, the Custom Local Address specify a process running in the same machine in case it tries to send packed to another local process? That can stay disable. So I fill the Custom Remote Address IP with the remote IP I want to grant access. I leave the port blank since for remote address I guess doesn't make sense to specify port. Once I specify the remote address the access is blocked.
Regards
