I was trying to capture localhost traffic with Ethereal, which doesn't work without re-routing localhost traffic to your router gateway. I didn't get the route command quite right, and messed up my routing table. I typed route -f to clear the routing table and rebooted, but when I finished rebooting, the routing table wasn't restored to its original state. I didn't use the -p parameter, so none of my changes should have persisted after a reboot.

What can I do to restore the routing table to its default routes?

Ethereal? Don't you mean Wireshark? –  Michael Hampton Aug 31 '12 at 22:34
    
Ethereal and Wireshark are both protocol analyzers. –  James L. Aug 31 '12 at 23:49
    
Ethereal was renamed Wireshark many years ago. If you're still using Ethereal, you have a real antique on your hands. And the provided link provides several possible ways of monitoring local traffic without messing with your routing table. –  Michael Hampton Sep 1 '12 at 0:58
    
Perfect! Didn't know that. I'll take a look. Thanks Michael. –  James L. Sep 1 '12 at 1:54

Turns out that because I had setup the IPv4 settings for the NIC to use static values, Windows didn't completely rebuild the routing table when I rebooted. I changed the NIC to get its address from the DHCP server, which rebuilt the routing table, then I set it back to static values again and rebooted. The routing table is fine now.

As a side note: This is the gentleman who created Ethereal... which went on to become Wireshark - serverfault.com/users/9470/gerald-combs –  joeqwerty Sep 1 '12 at 6:44
