<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hey Folk,</span>
<br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
I have an increasing situation that I'm looking to be proactive
about. I have a class C internal network at our office here, that due to growth
is running out of IPs, it's a 192.168.x.0/24 situation. I've come up with
two possible solutions, fell free to suggest others, it doesn't have to be a
free solution, just production quality.</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>1. Drop the
subnet mast to 255.255.252.0 or less, This gives me more IPs, and makes no
physical changes to the network, but requires me to reconfigure 250+ pcs,
servers, VPNs, VPN routes on remote sites, ect. This is not really desirable.
</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>2. Create a new
192.168.(x+1).0 subnet on a separate physical network and bridge the two with a
router. All new network drops would get plugged into this subnet.</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
The second solution is more appealing to me as it doesn't require
changing all the existing devices, except adding a route to a firewall or two.
The problem is I don't think I'm looking at a Cisco router in this situation, I
would want probably 2 GB interfaces one for the existing subnet and one for the
new and just have it route between the two, I don't want any packet filtering,
firewalling, ect. Just simple static routing. I don't seem to find GB ethernet
in the cisco routers unless you buy something modular and add cards, then It
has way too many features l don't need and starts to get pricey. I know I can
do the same with a Linux box with 2 cheap GB cards, even with an out of the box
Red Hat dist. There used to be a Linux Router Project but looks like it's
no longer maintained. </span><br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
Is anyone had a similar situation? How have you handled it. Is
there a better router / hardware device that I don't know of that does what I
want?</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Thanks</span> <br>
