I've found that getting good results from most P2P programs is easier when I'm not behind a router. I'm guessing this has to do with open ports.
Is there any simple way of getting things to work? Am I off base here?

You need to set up port forwarding. My Linksys router uses a web-based configuration, so in Safari I go to the router's IP addy, click on the Forwarding tab, and tell it to route traffic from, say, port 6346 (gnutella) to my iMac's address (192.168.xxx.xxx).
