Hi, I'm running NetBSD i386 with a small internal LAN, and 
a cablemodem to the outside. I'm getting a lot of messages 
that my arp info has been overwritten for NIC mac addresses   
on my internal LAN. I'm using 192.168.0.* as my internal 
subnet and it seems as though there are arp messages coming
in from outside. I have set up an ip filter and it is successfully
blocking a lot of packets destined for 192.168.0.*. The arp 
messages are still coming in though, which is causing my 
other machines to boot off the network, killing x sessions
and other nasty things.

Cany anyone help?
