Forge Multiplayer help

I understand that forge multiplayer is still a work in process, but I'm not having issues with the game crashing after connecting... I'm having trouble connecting to other people.
For me, when I create a server, it gives me the local address, 10.0.0.x:36743, which might be helpful if I was in the same network as the other guy.
When they create a server, they get a proper IP address, 192.xxx.x.xx:36743
In both cases, when we try to connect, we get the connection timed out error from forge.
How do I use what we have to get a proper address to enter? Rather, what format does your server address take when you're able to successfully connect?
Thank you for your help.
