First, I would test things out by adding an ifconfig alias (man
ifconfig) and adding a new route to the new gateway IP (using the route
command).
Then, once you're sure things are working, add an ifconfig alias in
rc.conf. You probably want the *new* IP to be the non-alias address, and
the *old* IP to be the alias. Make sure that defaultrouter is set in
rc.conf to be the new gateway IP. You'll need to also add the route for
the aliased IP to the route table using the route command. Then, test
away--make sure traffic from both IP blocks makes it through! Traceroute
is your friend! :)
(I'm not a total network geek, but IIRC, this is one way of doing what
you're looking for. If there are better ways of doing this, I look
forward to reading the replies and learning better ways! :) )
Best,
Glenn
