When I initially installed Fedora 8 I had this same problem. Unfortunately, I just kept poking it until it worked and have no real idea how I fixed it. Because I want to try Xen, I booted off the Xen kernel and the problem is back. (with that kernel)
<br><br>I can ping anything on either network, eth0 or eth1, but I can't ping anything on the other side of my linksys router which is supposed to be my default gateway.<br><br>Here is the ifconfig and netstat output from the regular kernel, which works.
