three bits of advice

1) Run the following commands, and look up how to interpret them.

  netstat -nr
  ifconfig -a

2) do you have a firewall of any kind configured?  why do you think the
number above is the IP address of (some) network interface?

3)

do

netstat -s > BEFORE
ping or whatever you think ought to work, for say 50 packets
# while doing this, do nothing else
netstat -s > AFTER

diff -u BEFORE AFTER

try to understand which counters changed and why.  This is a good way to
find error counters that increment in your situation, even if you had no
idea they existed.
