I have a FreeBSD 5.2.1 machine that has dual NICs. I would expect the following behavior if I placed both NICs on the same subnet (192.168.1.1 and 192.168.1.2 for example)... But in this case they are totally unique: NIC #1 - 10.10.10.1 255.255.255.0 NIC #2 - 192.168.10.1 255.255.255.0 Default gateway: 10.10.10.10 I am using a single SWITCH for all of my connections. most of my LAN is on the '10' block, but I have a few machines and 1 router that are on the '192' block. When I telnet into the freebsd machine from the '10.10.10.5' to the '10' block I see ARP comments on the console that I dont understand: arp: 10.10.10.5 is on fxp0 but got reply from 00:10:7b:80:04:40 on fxp1 How is this possible? - the laptop has NO IP on the 192 block at all. I understand how to shut up these errors using 'sysctl' - but I wanted to know why I am seeing them in the first place? -JDB
