Since "classes" are deprecated, and especially since m0n0wall doesn't
refer to them in any way at all in its interface, the CIDR (Classless
Inter-Domain Routing) terminology should be used.

So, you have a LAN on a /24 right now?  Do you want to add extra hosts
that are addressable by all those machines?  If that's the case, then
you need to change the subnet mask to a /23.  Simple, eh?  The joys of
CIDR!

Oh, don't forget to do an "ipconfig /renew" if these are all
DHCP-assigned Windows boxen, or whatever is needed to update the IPs on
all of these machines.  Changing the subnet changes the network, and
those with the old subnet (/24) will not be able to communicate with any
machines in the new part of that network.
