[ip-helper | Additional DHCP scope]

Hi,

I'm the only admin here and I need some advice please!

I have two sites on our WAN and both sites currently have a DHCP server issuing clients addresses at their respective sites. DHCP and DNS are running on Windows Server 2003.

I need to decommission the Windows Server at one site and then configure the router using ip-helper to route DHCP requests over the WAN to the other DHCP server.

I understand the concept but I have a question regarding the DHCP scope of the server now issuing addresses for both sites.....

So at the moment it only has one scope for it's local clients.... But do I need to define an additional scope on this server with the same network addresses as the local ones or must they be in the original scope of the other LAN?

So....

LAN 1

DHCP scope : 10.240.240.0/24

LAN2

DHCP scope: 10.216.114.0/23

becomes...

LAN 1

DHCP scope : 10.240.240.0/24

DHCP scope: 10.216.114.0/23

LAN2

ip-helper

or

LAN 1

DHCP scope : 10.240.240.0/24

LAN2

ip-helper

Does this makes sense? I hope I'm explaining this right.

Please help!!!
