DHCP Server and Clients across WAN

[Karthik S S]

Hello All,

Is it possible to have the DHCP server serving clients across WAN? If yes how to setup one?

Thanks in advance,

DHCP server must be located in the same subnet as the clients. Client broadcasting the DHCP request over the subnet and DHCP server takes it and answers the client. Client in this moment do not have routing table, no ip, nothing, so it can't get out the subnet.

While DHCP servers usually serve clients in
the same network, relay agents can be
configured to serve clients in different
network. Checkout the section on "DHCP
Configuration through BOOTP Relay Agent" in the
following doc:

Hi,

Typically DHCP Server configured for LAN environment. Technically it should possible, allowing the DHCP service in the WAN network.

I think, it involves routers configuration to allow DHCP service based requirement.
