Hi,

Amongst my hosts that have Internet facing IP addresses my Vigor 2820 appears to sporadically respond to arp requests with its own MAC address rather than letting than letting the host with that IP respond.

I'm running arpwatch on my network, so the router is generating all kinds of false positives with this behaviour.

Model Name : Vigor2820 series
Firmware Version : 3.3.1.2_232201
Build Date/Time : May 12 2009 14:42:43

Any ideas why the router is doing this?

Any ideas on how to stop it doing this?
