Changing Static IP Addresses

I need help with the steps to change our static IP addresses. We are
switching ISP's and installing a new SBCIS router. Our new ISP (the phone
company) will install the frame relay router but states that all LAN/NAT
issues are the customers responsibility.

Currently, we have Netopia router, an HP 4000 switch with 28 devices
connected to it. We are running a Win 2k server as a workgroup not using AD.
All suggestions will be appreciated....MG

It should be as simple as setting the LAN IP of the new router to an address
on your existing internal LAN scheme (perhaps the same IP as the old ISP's
router since I assume it will be going away). You should not have to change
any of your existing internal IP's.

You mean you are running public IP#s on the LAN itself?,....or you have a
NAT Device or Proxy between the LAN and the Internet with the Public IP#s on
on the "outside".

These are two entirely different things with two entirely different answers.

No, we are using private IP's on our LAN currently. We have a router that
does NAT (I think it is the router not the switch that does the NAT) from a
single Public IP address. Although we will have 30 Public IP addresses with
our new ISP we don't plan to use them until we upgrade to Windows SBS 2003.

I'm not a network person so please excuse if this is a dumb question. When
you say LAN IP do you mean the private address of the Router, switch, or
server???

Then nothing changes on your LAN. The LAN stays exactly like it is. The ISP
should be smart enough to know how to get you up and running.

We have 30 addresses too,...but in reality you can just about get by with
only one. There is no "exact" way to use the additional ones because it
depends on the type of new Internet Link you are given and how it is all
physically constructed. Trying to make use of additonal "public" addresses
is not the "panacea" that you might think.

Some routers are not set up no NAT out-of-the-box. If you own the new
router, then m,ake sure somebody knows how to program it. If the ISP owns
it, and won't give you access to it's programming, then /they/ should
configure it for you. Alternatively, you could try a cable/dsl router
between your LAN and the SBCIS, and let it do the NAT. Not 100% sure if
that'll work though.

Thanks for your help...
Our ISP installed the new circuit and router. The only thing I had to do was
to give them the ip address of our gateway private address. They reprogrammed
the router using NAT.... No changes were required to our LAN as you stated.

Very good.
Good luck with it.
