• What is DHCP Relay?
DHCP stands for Dynamic Host Configuration Protocol. In addition to the
DHCP server feature, the P-662H-D supports the DHCP relay function. When
it is configured as DHCP server, it assigns the IP addresses to the LAN clients.
When it is configured as DHCP relay, it is responsible for forwarding the
requests and responses negotiating between the DHCP clients and the server.
See figure 1.
• Setup the P-662H-D as a DHCP Relay
