I can ping localhost,ping public IP's....basically my Internet is working.But I am not able to connect to my router
Router addr given by ISP: 192.168.1.1
ping 192.168.1.1 is not working.
I could do so previously but few days ago it stopped working.
I am using ppp over ethernet and used the pppoeconf package to setup my internet.

route -n gives the following result:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
IP addr 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0

My gateway address is set to 0.0.0.0 and I am being set a public IP .

any help would be appreciated.
