[ale] Question on network

[James Taylor]

You're right so far.
If you change your network hosts' netmasks and your firewall netmask to 255.255.0.0, you'll be good on the local network.
However, you also need to change any route references from 192.168.11.0 to 192.168.0.0 so that incoming traffic will route to your new expanded address range.
If the firewall is on a router that is only using a default route, you probably won't even need to do it there.

Guys,

I need to as a question, I am weak on networking. Every where I have
worked we had a network guy, so I didn't have to deal with this much

Currently were I work I am about to run out of ip's, for now every is
192.168.11.0/24 lets say

We are using a Class C ( 10.11.0.0/24 254 Hosts Usable ), our head
program was us to move to a class B ( 192.168.0.0/16 65534 Host Usable
)

My question is this, I currently have a firewall that is my gateway,
it is 192.168.11.254/255.255.255.0

If I change all the ip's even the gateway netmask from 255.255.255.0
to 255.255.0.0 with it work with my gateway? Then can I use any ip on
the 192.168.0.0 range with my gateway.

So for example I set up the the following to use

192.168.10.0/255.255.0.0
192.168.11.0/255.255.0.0
192.168.12.0/255.255.0.0

I am currently reading a few books, but they aren't answering my question.

I like to be able for ip to work together with the one fireway. By the
way, I know that 192.168.0.0/24 is a private range for a class c, and
what I am talking would be better with 10.0.0.0/16, but I am use to
working with 192.168.0.0.
