You know you would get much more effective help if you posted exactly
what you are doing, and you posted config files and output from
ifconfig, etc.

A little further back you say that you tried to run the route command
but you did not say what the arguments to the command were.

You say that you have a bridge running but as far as I can see you
haven't posted any configuration info or ifconfig output or "netstat
-rn" output.  Nor have I seen where you've pinged by IP address, what
you've pinged in addition to mindspring.com, whether you've tried
traceroute, etc.
