3.4.2 DHCP Settings

DHCP(Dynamic Host Configuration Protocol) allows the individual client(computers) to obain the TCP/IP

configuration at start-up from the centralize DHCP server. You can configure this router as a DHCP server or

disable it. DHCP server can assign IP address, an IP default gateway and DNS server to DHCP clients. This

router can also act as a surrogate DHCP server(DHCP Proxy) where it relays IP address assignment from a actual

real DHCP server to clients.

If the DHCP was disabled, the screen of Fig 3.4.2-1 appears. You can enable/disable DHCP Server or DHCP

Proxy.

22
