How to properly set-up multiple NICs?

Hi,

Tnx for the reply!

Good! That's what I also thought, but I just wanted to be sure. :)

Yes, the main entry, i.e., the one for the outside world is set-up like 
this:
ifconfig_rl0="inet 123.45.67.89  netmask 255.255.255.0"
defaultrouter="123.45.67.1"
hostname="abcdef.nl"

My other two NICs are identified as re0 and sk0. When setting up one of 
them, say re0, for the local network I guess I only have to add an entry 
to /etc/rc.conf like:

ifconfig_re0="inet 192.168.1.1  netmask 255.255.255.254"

(note: the above gives a very restrictive netmask, as I'll only need the 
addresses 192.168.1.1 and 192.168.1.2).

Would the above be correct, or should there also be an additional 
defaultrouter entry, next to the one for the outside traffic (e.g. 
defaultrouter="192.168.1.1")? This wouldn't really make sense to me, as 
I guess that one would then become 'the' defaultrouter for all traffic 
(be it local or outside world)...

Cheers!
