It allows a remote access client to obtain an IP address on the intranet to which a VPN server's LAN adapter is connected if it is configured on the VPN server.

A DHCP relay agent is used to pass broadcast traffic across the two subnets. This means that when a client on Subnet B sends a DHCP broadcast message to obtain an IP address, the relay agent will receive the broadcast and forward it to the DHCP server on Subnet A. The DHCP server will then respond with an IP address and the relay agent will forward the response back to the client on Subnet B. This allows the client on Subnet B to obtain an IP address from the DHCP server on Subnet A without the need for a separate DHCP server on Subnet B.
