Well, I found that using an alias on my ifconfig line won't work for my
application -- I'm trying to set up a firewall machine, with two Intel
EtherExpress 100B's, and when I set up my /etc/rc.conf to configure the IP
addresses for each NIC, like so:

  ifconfig_fxp0="inet 10.10.138.224  netmask 255.255.255.192"
  ifconfig_fxp1="inet 10.10.138.225  netmask 255.255.255.192"

After booting up, I get the following message listed by 'dmesg'...

  arp: 00:a0:c9:2c:ca:5c is using my IP address 10.10.138.225!


QUESTION:  How do I set up a multi-homed host if not like the above?  Am I
missing something?

NOTE:  I don't want to alias two IPs to one Ethernet, since I want to block
all IP forwarding in the Firewall, and have it connected to two different
LANs...

Thanks for any help!
 Eric
