Ok, even though I have never used these two lines in the year my server has been going, they now say...
<address>68.169.188.17</address>
<localaddress>192.168.2.2</localaddress>
And it still doesn't work. I can log in fine if i'm AT the server, but I can't log in if I'm on a neighbors computer and no one else can. What next can we try?
