You could try traceroute, which should help you identify where the 
problem is.

You might also want to check that the nameservers in /etc/resolv.conf 
are correct. This file is generated by dhclient based on info from your ISP.

Also, be aware of the "-n" flag to ping, which causes it to not try DNS 
lookups. Your inability to ping the remote host may actually be ping 
trying to do a reverse DNS lookup on the IP address. This flag is also 
available for traceroute.
