Thanks for getting back those answers. I'd suggest you may have missed something. Perhaps in your port forwarding. You must set up a Static IP Address or else the next time you log onto the computer it will be allocated a different address & your efforts will have been in vain. In the link here on the 1st line there's a link to how to create Static IP Address: Port Forwarding for the Linksys WRT54G v1.1, v2 & CA
& don't forget to save your settings. I don't use the same type of router but with some you also need to reboot the modem-router after you've made these changes. Oh & of course use Port 6346

Oh I posted the wrong model for a minute! wrv instead of wrt lol
