clients on the network, it provides vendor-specific configuration and service information. The 

 provides a list of DHCP options by RFC-assigned option 

number.

The SonicWALL DHCP server options feature provides a simple interface for selecting DHCP 
options by number or name, making the DHCP configuration process quick, easy, and 
compliant with RFC-defined DHCP standards.

The SonicWALL DHCP server options feature allows definition of DHCP options using a drop-
down menu based on RFC-defined option numbers, allowing administrators to easily create 
DHCP objects and object groups, and configure DHCP generic options for dynamic and static 
DHCP lease scopes. Once defined, the DHCP option is included in the options field of the 
DHCP message, which is then passed to DHCP clients on the network, describing the network 
configuration and service(s) available.

The SonicWALL DHCP server options feature supports the following standards:

RFC 2131 - Dynamic Host Configuration Protocol

RFC 2132 - DHCP Options and BOOTP Vendor Extensions

The following sections provide an overview of the Multiple DHCP Scopes per Interface feature:

Often, DHCP clients and server(s) reside on the same IP network or subnet, but sometimes 
DHCP clients and their associated DHCP server(s) do not reside on the same subnet. The 
Multiple DHCP Scopes per Interface feature allows one DHCP server to manage different 
scopes for clients spanning multiple subnets.

Efficiency – A single DHCP server can provide IP addresses for clients spanning multiple 
subnets.

Compatible with DHCP over VPN – The processing of relayed DHCP messages is handled 
uniformly, regardless of whether it comes from a VPN tunnel or a DHCP relay agent.

Multiple Scopes for Site-to-Site VPN – When using an internal DHCP server, a remote subnet 
could be configured using scope ranges that differ from the LAN/DMZ subnet. The scope range 
for the remote subnet is decided by the “Relay IP Address” set in the remote gateway.
