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.
