The FAQ in my sig might be of some help. Basically, it sounds like your issue is that your ports are either not forwarded properly, or you are running some type of firewall that is blocking the connections from the outside. If you setup your server as a DMZ in your router/modem, then it should be working. At that point, the only thing I can really think of that would stop people would be firewalls, including the Windows build-in firewall. Try making sure you have it and any other firewalls disabled. If you run a security suite or something like that, it could be blocking them as well.
Also, after looking at your config, I noticed you have this section uncommented:
Code:
<address>some.server.com</address>
<localaddress>192.168.0.1</localaddress>
That is only to be used it you run a mini-login server. If you are running a server that people connect to from the Public Login Server, then you do not ever want to set those settings. They will always mess up connectivity. Either remove those from your config or comment them out again. There is a reason why it says the following line right before that part of the config:
Code:
<!-- Only specify these two if you really think you need to. (read: You don't) -->
In other words, you don't need to set those 2 and it will cause problems if you do.
