2 internal subnets

I currently have our entire office on the subnet 192.168.0.1. However we are
growing very fast, and I need to expand. I have read many articles where
they talk about having servers on a subnet of 10.10.1.1. How do you get two
seperate subnets to talk to one another?

Your network is probably 192.168.0.0 with a mask of 255.255.255.0. The
network you're talking about using instead is 10.0.0.0 with a mask of
255.0.0.0, which would allow you many more addresses within your network
space.

But if you're really growing fast enough that you're overrunning your
192.168.0.0 network, you probably really need to hire someone who really
understands the networking stuff, no offense.

You need a router Daniel. Routers forward packets destined for other network
segments. In your case you have a network segment 192.168.0.0 255.255.255.0,
which would send packets destined for systems not on that net to the router.
The router would then forward the packets to the corrected network or if not
known use its default route.

You can use the 10.x.x.x network if you want in a class C environment by
simply changing the mask. This will allow for 254 more hosts per net you
subnet out. An example might:

10.192.168.0 255.255.255.0/24

You see? Pretty simple if all you want to do is modify your internal LAN to
a second subnet. Just make sure to forward broadcast traffic on your router
or DHCP, etc won't get forwarded. This is usually not defaulted to "on".

Hope this helps...

Having two subnets is not a big deal. The important bit is getting them
configured correctly so that the two subnets can both see the outside world
and each other.

Since you talk about internal subnets I assume that you connect to an
Internet router. This router may be able to handle this itself. If the
Internet router can handle multiple LAN subnets, the setup is simple.

Internet
|
Router-------------------------------------
| |
192.168.0.1 192.168.1.1
| |
workstations workstations
192.168.0.x dg 192.168.0.1 192.168.1.x dg 192.168.1.x

If your Internet router can't handle it, you will need an additional
router between the two subnets. You will also need an extra route on your
Internet router so that it knows how to reach your new subnet. eg

Internet
Router
192.168.0.1 {static route 192.168.1.0 255.255.255.0 192.168.0.n}
|
workstations
192.168.0.x dg 192.168.0.1
|
192.168.0.n dg 192.168.0.1
internal
router
192.168.1.1 dg blank
|
workstations
192.168.1.x dg 192.168.1.1

No you don't need 10.*.*.*

You just use another 192.168.*.*

Buy a LAN Router (not a Home User Broadband NAT box)

Add another segment using 192.168.1.*

The LAN Router becomes the Default Gateway of all Hosts.
The Internet Sharing Device becomes the Default Gateway of the LAN Router.
The Internet Sharing Device uses a Static Route to tell it to use the LAN Router
for all your LAN's segments. The router would look like:

192.168.0.0 mask 255.255.0.0 <IP# of LAN router>

Keep LAN Segments below 250-300 hosts. The normal subnet mask of 255.255.255.0
does that perfectly fine with 254 usable hosts.

With all that said,...if you don't understand the above, you need to get help as
others have suggested. We can't teach you an entire 2-sememster school term's
worth of routing skills in a newsgroup email message,...it just isn't possible,
there is too much involved.
