Failed to determine external IP adress

I just downloaded Factorio from Steam, and tried playing multiplayer with a friend, but I got this error. I don't know what's causing it. I bypassed my firewall, forwarded the port 34197 (at least I think I did). I haven't found anything helpful on the internet about this.

I haven't played Factorio since it went on Steam, but I didn't have any problems playing MP before that.

Log

P.S.: I just noticed in the log that Factorio apparently loaded the FARL and RailTanker mods twice, but I don't think that has anything to do with my problem.

I think I'll take part to this conversation also. I've been played factorio some time now, and thought, in the group it could be even more fun!

I've familiar with port forwarding stuff, and set up necessary UDP:34197 forwarding to my router.

Here's part of my config file:

Code: Select all

And here's factorio log after launching multiplayer game:

My IP address is correct there, and actually people can join on my server, when they connect directly with IP from "Connect to server"-option.

But why the hell it messes up the port, that it think server is running, if port is defined for 34197?

because the outgoing traffic is probably being NATed by your router. disable outgoing NAT if you can.
most SOHO routers suck for hosting any kind of server.
