PPP Routing?

[Alex Ronald Swanson <aswanson mail utexas edu>]

HELP!!!

I can connect to the internet and
ping my nameserver address, but I
cannot ping or connect to anything
else.

The PPP HOWTO says that I should
explore my system initialization
files to find out where the default
route is being set
up.  I have RedHat 5.1.  Tell me
what I have missed.  Here is the
output from my ifconfig and route
commands:



[root localhost /root]# ifconfig
lo        Link encap:Local Loopback

          inet addr:127.0.0.1
