Factorio Port Forwarding

[GalteN Hasse]

Both me and my friend has tried portforwarding for factorio, we've used the port 34197 and set the protocol to "udp only" and just in case that made some errors "both" ive also tried turning my firewall for ipv-4 off to make that not collide with factorio but still no one can connect to my server. I reckon something is wrong with the ports, atm i have put
External Port [34197] Internal Port [34197] Protocol [UDP]

VPN solutions are always slower than portforwarding, so i wouldn't recommend. Factorio is already quite dependant on low ping.

Here's what a rule looks like for me: http://i.imgur.com/PgHStqE.png
Just a few fields you need to fill and you're done. Calls for a real IT expert imo xD Obviously the window looks different per router. And you need to know your current LAN IP, there's several ways to find it too, one being "ipconfig" in command prompt, other in checking the router clients.

Generally only server host needs to do port-forwarding, but if it's peer-to-peer between 3 players then i don't even know. 2 of them might need to do it? One player can alternatively download a dedicated server and run that for them all.

Common router ips:fritz.box, 192.168.188.1, 192.168.188.2, 192.168.0.1, 192.168.0.2, 192.168.2.0, 192.168.2.1

If you are not sure if your port is open, use this tool > http://www.canyouseeme.org

But opening ports is more risky :P

Actually canyouseeme.org didn't find my factorio server when it was correctly open. It's the first time i've seen that happen for any game server. Friends can join it just fine though. Maybe that website doesn't support UDP?

As for opening specific port in router a security risk... If you are able to start factorio server, it means no other system process is using the port. Therefore from that port no attack to any service can be made.

Worked fine for my servers

But dont forget that then the server has too be online all the time, would be nice if factorio could open the ports itself via upnp ^^
