Hi there, quick question. A have a FreeBSD version 3.1 box with 3 network
cards. In linux when doing an arp -a it distinguishes ip, hardware address
and interface like this:
dial-84.ocis.net (209.52.173.216) at 00:C0:05:04:16:1A [ether] on eth0

but on a FreeBSD system it doesn't seem to distinguish what interface only
ip,and hardware address like this:
	gateway2.ocis.net (209.52.174.254) at 0:10:7b:ba:f0:61

Does freebsd seperate arp entries by interface like linux? The reason I'm
asking is (i think) in linux you can have an arp entry for the same
ip-address but on different interfaces like this:
dial-84.ocis.net (209.52.173.216) at 00:C0:05:04:16:1A [ether] on eth0
dial-84.ocis.net (209.52.173.216) at xx:xx:xx:xx:xx:xx [ether] on eth1

This is useful for proxy arping two networks together and making it appear
as one network. (Without using natd or bridge). Can this be done with
FreeBSD?


Thanks ...
