Thanks! The solution came by way of a local radio computer support talk show where one fella knew that Roadrunner had changed their DNS servers without telling anyone. I'm still in the dark about why this doesn't affect the computer directly connected to the cable modem, but the masqed computers definitely needed the updated IP numbers for DNS.
Thanks, Mike Holloway

It almost sounds like your PC(s?) have changed their configuration, such as trying to use a proxy that is not available.
The best way I know to debug a problem like this is "tcpdump".
For instance, on the masq gateway, open two windows, one showing inside packets:
tcpdump -n -i eth0
And another showing outside packets:
tcpdump -n -i ppp0
This assumes your internal/external interfaces are eth0/ppp0, of course.
Then, when you begin a web request on the PC, watch the screens. Do you see the port 80 traffic on the internal side? Do you see corresponding traffic on the outgoing side? Do you see the RETURN traffic coming back from the web server? Do you see that return traffic being forwarded back to the originating machine? You should be able to see the IP addresses change due to masq, as well.
Watching this process happen in real-time is a great way to find out WHERE the problem is occurring, and this will lead you closer to the solution.
