In a nutshell, I'm trying to host a multiplayer game. I host the game, the server browser can see me, and my friend can see I'm hosting a game. However, when he tries to connect to me, or vice versa... The game simply reports that it cannot connect to server. No information beyond that. I've tried...
Forwarded Port, and verified that Factorio uses UDP 34197
Got my friend to host, same error.
Verified that there are no firewalls built into my Modem, or that my modem supports NAT. (It does not)
Verified the built-in Windows Firewall isn't blocking anything. It is not.
Connected to a random vanilla server. I was able to connect, I did not get my friend to test, as the game name was in Japanese characters.
Killed Windows Built-in Firewall, and tried again.
Verified with my ISP that there are no additional protections involved that would prevent a connection like this.
The logs just don't provide much information. As I understand, I handshake with Factorio's Ping Pong servers, but when Ping Pong gives the client the IP, the server just never responds.
