Router Question

I recently purchased a LinkSYS EtherFast Cable/DSL Router. My father already owned a NetGear RT314. Both of us share our internet connection along with sharing files at our house. My question is this....Ever since I installed my router, my father is unable to connect to my personal FTP site and we can no longer NetCam either. Now I know that the router makes a private network for all the PC's connected to it to share the internet connection but how can I get around this. Mainly what I'm asking is what do I have to do for my FTP to work agian and how can I Netcam? Thanks for any help.

Do you have both routers installed? If so, why? You should only have one router installed (you probably could have both installed, but there's usually no need, and it adds another layer of complexity to your network).

When to try to access each other on the private network, you actually have to specify the IP address of the machines on the LAN (those routers mess up internal connections using external domain names... probably a side-effect of NAT)...
