Error #10049!

[rice chrisp]

Long time client, first time server user here. I've been struggling to get my server up and running for my guild (in WoW) since yesterday afternoon and sifting through the various manuals and FAQs here and I thought I was making progress until I saw this:

I started receiving this error after I edited my server.ini file, this line specifically:

BoundToIp1=67.139.91.84

I have 2 IPs under the "Your IPs" menu.
192.168.1.101 (which obviously is my private IP)
and
67.139.91.84 (the IP I give out to my guildies of course)

The reason I changed the BoundToIp line was because leaving it blank didn't seem to help, i.e. I could log on but none of my guildies could when I gave them the WAN IP. However, changing it (as has been suggested in the FAQs and a bunch of threads in these forums) only seems to have made things worse! :(

Any help you experts could offer would be greatly appreciated, thanks :)

P.S. I have a NetworkEverywhere Linksys router, model # NR041 and already went in and tweaked the port triggers to get 8767 opened up.
