It sounds like your upstream setup is configured to allow only one computer
at a time?

If this is the case, test with just the PAP2, with the Linux machine
disconnected from the hub.  Until that works, you probably won't get it to
work through Linux.

Seems likely.  Although the masquerading isn't provided by the DHCP, you
need both.

Now, back to your regularly scheduled experts, like Kevin, who actually
know how to set up TCP/IP.
