Scenario 3

The following describes this scenario:
When a local LAN user requests IP information, the DHCP server (not
the RAS 1500) sends it to the user.
When a dial-in user requests IP information, the RAS 1500, acting as a
proxy server, relays the request to the DHCP server. The DHCP server
processes the request and sends the IP information to the RAS 1500,
which relays it to the dial-in user.
