configure Redhat 9 for static LAN IP and DHCP dynamic IP dial-up modem

["Ralph E. Kenyon, Jr." <diogenes xenodochy org>]

I have been using my Redhat 9 system on my home LAN with a static IP
address (as a web development server).  I'm still quite new to Linux.
Now I want to be able to stay on the LAN in the same configuration, but
add a dial-up connection that will support DHCP from my ISP.
So far, I have been able to get my wvdial to connect and start PPP,
showing me the IP address, but after that nothing else seems to work.
I can switch to another screen and ping either of the two IP addresses
shown, (obviously one is mine, and the other is the ISP), and I can ping
the other static IP addresses on the LAN.

How can I get my browser to work when I switch to the X-window?
I suspect I need to do some more configuration for hosts? DNS? etc.?

Any help would be appreciated.
Thanks,
