Thanks for the reply codeman!
I did set both those values during setup, but you gave me a clue that fixed it!
I'm using an external IP in my Config.wtf to connect to an TC server that's internal to my network. There's no firewalls on my windows client or my TC linux server, but my router does a NAT bounce when using the external IP. What I forgot was to open the new ports (1119, 8081 and 8086) in my routers forwarding.
I just connected now, and I'm able to connect to the realm and create characters. Thanks again, you guys are awesome!
