vnc has problems with router?

[QUINN MCKINSEY]

Sorry, on my initial post I gave no mention of vnc in the title.

I have been trying to setup the vnc server on windows XP.  I have the ip address, but for some reason connections cannot be made to the server.  I am using a labtop to try and figure out what is wrong.  So far, I think the problem may have to do with the router because when the labtop is connected to the router I can connect to the server and everything runs fine, but if I try to connect over the internet, thus comming from outside the router, nothing works.  However, the labtop is also a server and I have been able to connect from the windows XP to the labtop over the internet.  I have disabled my firewalls on the XP, but it seems to have no effect.  I am using a linksys router, but I don't see why it would only allow connections in one direction.  Any help would be appreciated.

Thanks
