You need to set SonicWALL LAN and WAN in Layer-2 Bridged mode.<br />

In the sonicwall it's under ip helper. Here is a write up direct from dell (sonicwall) <a href="https://support.software.dell.com/kb/sw3793" rel="ugc nofollow">https://support.software.dell.com/kb/sw3793</a>

Layer-2 bridged mode? No that's just wrong.

Indeed you need to create IP Helper policies.<br />
Go to Network&gt;IP helper<br />
Enable IP Helper<br />
Enable DHCP protocol<br />
add a policy with src = the subnet or interface<br />
and destination the DHCP server<br />
<br />

Recently, we have setup a Window DHCP services. How can I configure the Sonicwall such that it will use the Window DHCP for both LAN and Wifi subnet ? Any example for reference.<br />

DHCP relay on Sonicwall

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

DHCP

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
