Scenario 5

The following describes this scenario:
When a local LAN 1 user requests IP information, the RAS 1500 A,
acting as a proxy server, relays the request through the PSTN to the
RAS 1500 B. The RAS 1500 B relays the request to the DHCP server on
LAN 2. The DHCP server processes the request, then sends the IP
information to the RAS 1500 B. The RAS 1500 B relays the
information to the RAS 1500 A. The RAS 1500 A relays the
information to the local LAN 1 user.
When a local LAN 2 user requests IP information, the DHCP server
sends it to the user.
When a dial-in user to the RAS 1500 A requests IP information, the
RAS 1500 A, acting as a proxy server, relays the request through the
PSTN to the RAS 1500 B. The RAS 1500 B relays the request to the
DHCP server on LAN 2. The DHCP server processes the request, then
sends the IP information to the RAS 1500 B. The RAS 1500 B relays
the information to the RAS 1500 A. The RAS 1500 A relays the
information to the dial-in user.
When a dial-in user to the RAS 1500 B requests IP information, the
RAS 1500 B, acting as a proxy server, relays the request to the DHCP
server on LAN 2. The DHCP server processes the request and sends the
IP information to the RAS 1500 B. The RAS 1500 B then relays the
information to the dial-in user.
