New Default Gateway via DHCP in stages

Hi All,

We are replacing our Default Gateway over the weekend.  The new Gateway has a new IP address to the old one, as we want the option to role back if there are issues.

My question is;

Is there a way to give 20 specific users the new gateway using DHCP and leave the rest on the old gateway?

I thought I could take 20 IP's out of the current range and setup a new scope on a new DHCP server and use reservations to give them out.  But the users appear to go to the quickest server to respond, which isnt always the quickest.


Many thank

Something like MAC filtering may work for your purposes: http://technet.microsoft.com/en-us/magazine/ff521761.aspx

How do I make it only use the new scope?

Sorry, I misread that you were changing DHCP servers as well. What about creating static reservations for your test users that use the new gateway?

I don't have to create the new server, I only did it because I didn't think you could create a second scope with the same subnet on the same server.

I tried doing it using reservations, but this only works when the new server responds. So if it can be done on the one server that would make it a lot easier.

That's what I mean, using a single server, create DHCP reservations for specific clients with the new IP. If things break, just delete the reservation.

How do I get the reservations to get the new default gateway?

I'm assuming that you're using Windows Server for your DHCP. You'd create a new Reservation as normal (right-click Reservations, New Reservation) and then edit it (right-click, Configure Options), then add the "003 Router" option with your new DG.

Ah, I was trying to edit the existing Option, but adding a new one overwrites the original.
