DHCP
RELAY :
In the IP router mode, you have the opportunity to Enable a DHCP relay server as an
alternative to the DHCP server. The DHCP relay server is used for forwarding DHCP
requests via an Ethernet segment
. All interfaces, on which DHCP requests are received, as
well as the interface, on which the actual DHCP runs, must be selected in DHCP relay
mode.
Automatic relay IP:
If this function is activated, the firewall itself works as a DHCP server and responds to
requests from the selected interface.
Relay IP address:
Here you'll have to enter the IP address of the DHCP server.
