Should I subnet.

By abernut ·
I know everyone loves to subnet.

Right our company's local LAN is set up using a standard Class C network. We have two other sites coming online in the near future. I would like to keep everyone on the same network and create child domains for the two new locations on the same network but different subnets.

My question is.....

How much of a pain in butt is it going to be to change my current IP configuration to the one I have in mind, for example. My local LAN is 192.168.30.0 /24 and I want to change to 172.28.0.0 /21 giving me 30 usable subnets with 2046 hosts.

I have multiple Win2003 servers, a router acting as a public router, a Watchguard X700, and many workstations.

Is it worth the time or is there a better way.

Thanks in advance

Mike

Have you considered VLANs?

by shirtbird In reply to Should I subnet.

I have found that VLANs with a router-on-a-stick configuration is 100% easier than subnets...have you considered using them instead?

Router Config

by abernut In reply to Have you considered VLANs ...

Is this an option with my Router being configured as a Public Router(Public IP on FastEthernet Port and Public IP on the Serial Port?) My Watchguard X700 is acting as my default gateway which has another Public IP on its External Port and a Private IP on its LAN part ie. 192.168.30.1.

Possibly

But I'm not sure it would be considered best practice - most likely you'd need/want to purchase another router to work internally.
