DHCP Relay
With this webpage, you can enter a list of IP addresses for DHCP servers. When a client requests an IP address,
it uses one of the DHCP addresses listed in the DHCP relay webpage. The Black Box forwards (or ‘relays’) the
request to the DHCP server.
Note
Do not use the Black Box’s DHCP server if the DHCP Relay is enabled.
Configuration of the DHCP Relay
The DHCP Relay webpage has three sections. (See
figure 64
.)
•
Enable/disable: The button in the first section enables or disables the DHCP relay on the WAN
Access Router.
•
Edit DHCP server list: The IP addresses of DHCP servers can be updated, reset, or deleted from the list.
•
Add new DHCP server: the IP addresses of the DHCP servers are added to the DHCP relay list in
this section.
