I want to use a DHCP relay agent as we are moving building and the Pcs moved
to the new building I want them still to get their ip from the server in the
old building. We have a firewall which sets vpn tunnels between the 2
buildings, we could setup a dhcp on the firewall in the new building, but I
want to see the affect of using w2k dhcp relay agents, where could we
install this and most imprtantly we dont use RRAS but would be the affect on
our network if we enable RRAS.
 
The Relay Agent could ideally be set up anywhere where the DHCP broadcast
will be seen by the Agent. This means an interface must be on the local
segment that the clients are on. Normally, you'd install the Relay Agent on
a box that is routing between two subnets.

------------------------------[DHCP Relay]------------------------
|>>>Broadcast>>> >>>Unicast>>> |
{client} {DHCP
Server}

however you could also do this scenario:
Unicast>>>>>>>>>>>>>>>

---------------------------------------------[ROUTER]--------------------
| >>>Broadcast>>> | ^ >>|
{client} [DHCP Relay] {DHCP
Server}

In the this scenario, you listen on the interface for the DHCP Discover
broadcasts, and resend them out as unicasts to the DHCP Server.
