If you NAT is moderate, this usually means that your network is restricting certain ports, and therefore certain packets the game wants to send. Redacted or the client you are using could be running on a port you have closed, and therefore packets cannot be sent or received on the port... Self explanatory really. Give getting an Open NAT type a try (usually done by putting the IP of the computer into DMZ mode on your router or search for the ports needed in order to open NAT type for the specific game on your specific router)
Did you make a PC based rule or a router based rule? I doubt making one on the PC will have grave importance, you need to follow something like this:
Oh, I now understand.It was a PC based rule, since the router isn't involved. I connected the machines with only a cable between them. And disabling the firewall as I said, doesn't fix the problem.
I'll be sure to check it out! Thank you!
No I haven't tried "DMZ Mode" yet, since I am trying to get it working machine to machine with only a cable. But I will be sure to test it later
