I have a COM21 and I have the same problem. You'll notice that the TX light on your NIC will never stop. It never used to be a major problem with my ne2k-pci NIC (until the NIC got toasted for one reason or another). After that I switched to a 3c905*, which seemed to work great but would go dead after about 15 minutes (presumably because of the arp bombardment). My solution was to reset with interface with a cron job every 15 minutes. It's a total rat-fsck solution, but it works. > > This makes me nervous. 212.127.*.* is my ISP cable modem network.

If I tcp dump I see many 'arp who has xxx.xxx.xxx.xxx tell xxx.xxx.xxx.xxx' and the ip addresses jump around all over the place. Not sure how to stop it. g
