Server Making With the Server Wizard

[Link]

Firstly, I would really strongly suggest reading through http://assault.cubers.net/docs/server.html before running a server.
As for the error message you got, it means that either 1) your ports are not forwarded or 2) some firewall is blocking AC. I would suggest looking at http://portforward.com/ for the port forwarding, and make sure no firewall is blocking AC.

ya, sure, but what if i have parental controls......
