DHCP

The firewall supports the Dynamic Host Configuration Protocol as defined in RFC 2131 (IPv4) and RFC 3315 (IPv6). You can use DHCP servers to dynamically allocate unique IP addresses to devices on a network. Using a DHCP relay, you can provide dynamic address allocation for clients that are not on the same subnet as the DHCP server. You can also view lease records.

A DHCP server assigns a unique IP address from a specified range to a host and releases the address when the host leaves the network. Once an address has been released, it can be reused. You can also configure the server to assign static addresses. Use a DHCP server to service clients that are on the same subnet as the server.

• To create a DHCP server, go to the Server section and click Add.

A DHCP relay agent enables DHCP clients to obtain IP addresses from a DHCP server on a remote subnet or from a server which is not located on the local subnet. Use a DHCP relay to service clients that are on a different subnet than the DHCP server.
