You shouldn't need to set a gateway in order to ping 172.21.0.1 because
you should have a direct connection to it. Your initial routing table
looks like it should work so I'd suspect another problem. That said, the
final line isn't right if you want to contact the outside world.
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
should be:
0.0.0.0 172.21.0.1 0.0.0.0 U 0 0 0 ppp0
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
172.21.0.1 0.0.0.0 255.255.255.255 UH 0 0 0
ppp0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0
eth0
0.0.0.0 172.21.0.1 0.0.0.0 UG 0 0 0
ppp0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0
ppp0
yeah, the final line looks dubious to me too, but i wasn't sure.
however, if i make the changes u r suggesting surely the 3rd and 4th
lines will only differ on the "G" flag? that doesn't look right either!?
You said you can connect fine using ppp alone - what does the routing
table look like then?
i can connect fine to the internet from the gateway. This is what it
looks like.
