Assuming you have two LANICs installed, yes.  We always had 2 LANIC
cards in our 950s (initially you had to have one for DTS and one for
TCP/IP).  You add another LINK in NMMGR with the path of the new LANIC,
then configure protocols/gateway for it, using a different IP address
from the first, and with a different NET= name (if you like).  I used
this approach when we changed our IP addresses; we configured the router
with the "new" address as a secondary.  I configured our original
DTSLINK for TCP on the old address and changed the other link's TCP
addresses to the new ones.  Shutdown and restart the network, both nets,
and the 3000 answered to both addresses.  As soon as the user PCs were
adjusted and DNS updates settled down, I just removed the old address
configs from the DTSLINK.

With two cards, you can almost "hot-swap" from card to card in the event
of a failure; but moving DTSLINK requires a reboot (or does it in 5.5?)
and moving TCP requires a :netcontrol update (or is it stop/start?).
You just can't have multiple addresses on the same LANIC (or can you?).
Just keep your two configurations separate.

Another consideration, if the two LANICs are on different logical
networks (two different class-C addresses for example) and you don't
want any forwarding done by the 3000, you must set the store-and-forward
buffer counts (in NMMGR) to zero.  I don't think it will forward (route)
packets automatically, but you can enable this too (someone else will
have to step in for me at this point).
