Hi Terri,

I tried route del default and then route add default
xxx.xxx.xxx.xxx after which it looked like

Destination     Gateway     Use Iface
0.0.0.0     xxx.xxx.121.254   ppp0

I also found the entry nameserver kitkat & it's eth0
IP 198.1.1.0 in there. Both of which I blocked.

But it still can't ping any host.

Well, please let me know how can I add my ISPs
nameserver in /etc/resolv.conf so that it can catch
the nameserver from the void.

Or any further help would be greately appreciated.

-T.
