Hi

Is your gateway correctly configured? What do you see it you do

netstat -r

in a terminal?

Here's mine:

Destination Gateway Genmask Flags MSS Window irtt Iface
169.254.255.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default 169.254.255.100 0.0.0.0 UG 0 0 0 eth0


If you do not have a line with a UG in the "Flags" column, your gateway isn't correctly configured. You said you can ping your router, right? That means your local setup is most likely ok, you just need to setup the gateway.

To do that, at least in Redhat Linux FC3, edit

/etc/sysconfig/network

and make sure it looks something like this:

NETWORKING=yes
HOSTNAME=StefanLinux
GATEWAY=123.456.789.123

Where, of course, the GATEWAY adres is the local address of your router which is connected to your local ethernet.

Hope this helps...
