Enabling DHCP
Note: This topic applies to the Inverness Release.
The Smoothwall's Dynamic Host Configuration Protocol (DHCP) service enables network hosts to automatically obtain IP address and other network settings.
Note: Note that a Unified Threat Management serial is required to make use of the DHCP service. For more information, contact your Smoothwall representative.
The DHCP service provides a fully featured DHCP server, with the following capabilities:
|
|
Support for 20 DHCP subnets |
|
|
Allocate addresses within multiple dynamic ranges and static assignments per DHCP subnet |
|
|
Automate the creation of static assignments using the ARP cache. |
You can use the DHCP service in either Server mode, or Relay mode:
