Shared Internet Connection Using Static IP's

Hi, I'm trying to setup a shared internet connection on my network at work.
We are currently using an old 3rd-party proxy server on a dial-up on a
Win2000 server. It works but is no longer an option because of the nbr of
people using it.

The ISP just installed the Internet modem and antenna on our bldg that
connects to our ISP. The problem is the connection to our network. We have
a class-B subnet with static IP's. The ISP wans us to change everything to
DHCP which will cause a lot of work trying to make everything "happy". Our
IP's are 172.20.x.x & 172.21.x.x with a subnet of 255.255.0.0.

What is the best solution that will retain our static IP's?

USR has a router (Model 8200) that will handle a class-B setting at a cost
of approx $300.00. This is a pretty expensive test if it does not work.

It looks like I would have to use DHCP if I use the built-in connection
sharing in Windows.

Does anyone have any experience/advice on how to handle this?

Thanks in advance!
Carl

if you have windows 2000 server license, setup RRAS separating the network
and keep the class B.

Thank you for the advice. We do have a Win2000 server license and will be
going to Win2003 next spring. I didn't think about the RRAS solution but
will investigate it!

Thanks again!
Carl

You could buy a $50 NAT Device to spearate your LAN from the ISP and
accomplish the same thing. I suspect Robert suggested RRAS because we would
have assumed you already had that in place an would have not had to buy
anything, so it would have been "free".
