An "IP directed broadcast" means a broadcast to a specific network or
subnet, for example 172.16.255.255 or 172.16.10.255. It's a generic
concept, not specific to DHCP.

Great little hack, Ejay!
The other idea, if you're migrating IPs, is to just shorten the lease time.
Say your normal lease is 7 days, then 6.5 days before you're planned
migration change the lease time to like an hour or so.
The other migration method is to use ip address secondary and just let

Sure, the first one that responds wins.
They don't even need to be on the same physical network. Let's say that you
have DHCP Server #1(10.10.10.10) in the production site and DHCP Server #2
(192.168.1.1) at your DR site.
The router is configured with a helper address for both:
ip helper-addr
Try the IP Helper again. That should work for you. I can't think of any
reason why the IP Helper shouldn't work.

Can't think of much that would stop it either as long as you have a scope
set up for the interface which you put the ip helper address on.

What kind of WAN? Frame, ISDN, leased line, etc.? Who is the service
provider? Is it a VPN? It should work, but maybe there's

The ip helper-address is the right direction. Are there any filters on
the WAN side, either on your router or at the ISP? You need UDP port 67
enabled for your setup to work. As for the ip forward-protocol command,
when you enable the ip helper-address, several protocols get forwarded,

You can set a static pool based on mac address.

No you haven't been doing that thing with the fumes. On Windows NT Server's
DHCP Manager I know that you can use a NetBIOS scope ID to assign IP
addresses to different subnets/networks. I don't know much about other DHCP

This is very easy to set up. Create a scope of addresses that you want to
asign to DHCP clients at your remote site.
Set up IP helper-address at the remote site pointing to your DHCP server.

Yes this is true. On the remote router you would add
the command:
"ip helper-address X.X.X.X"
The X.X.X.X is the address of you DHCP server or the
LAN segment that it sites on.
When the client does a DHCP request it is broadcast on
thier local segment. The router sees this request and
picks
You can use IP forwarding on the router to the DHCP and set the scope on the
clients and server so that it picks up addresses in that scope from dhcp, OR
you can use DHCP on the router to assign addresses to the clients preventing
broadcasts for DHCP across the WAN link.

Pat,
This is a correct solution so don't worry about inhaling the fumes, it's
probably good for you. Seriously, the last office we setup from boston, Ma
to franklin, Tenn was setup with frame-relay to an enterprise N/T domain, we set-up a
