You wrote in and said you did later on. I'm beginning to wonder if you don't have a loop in your network. I'd like to see the output of 'netstat -rn' again after the changes we made here. Also, if possible, crank up two tcpdumps, one on each interface. Then do something that illicits the error and check the dumps.

Stuff is going where it's not supposed to. I assume your Cisco is a router and not just a TA.
