The two thoughts I have are:
1) Did you correctly enter the info about your default gateway? If you did, your routing table (run the command route -n
) will have an entry similar to the following:
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.1.123 0.0.0.0 UG 0 0 0 eth0
where, in this case, the default gateway is available via eth0 at 192.168.1.123
2) Are you sure
your DNS is configured properly? If item (1) was correct, try the following 3 commands:
If the first two work, but the third does not, you have DNS problems.
Good luck. Post back with more info if you still have problems.
