Configuring the SonicWALL DHCP Server
To configure the SonicWALL DHCP server for the WorkPort, the HomePort, or both, complete the
following instructions.
1. Select the Enable DHCP Server.
Alert Make sure there are no other DHCP servers on the WorkPort or HomePort before you enable
the DHCP server.
2. Enter the maximum length of the DHCP lease in the Lease Time field. The Lease Time
determines how often the DHCP Server renews IP leases. The default Lease Time is 60 minutes.
The length of time can range from 1 to 9999 minutes.
3. If configuring DHCP server for the WorkPort, enter the gateway address used by WorkPort
computers to access the Internet in the WorkPort Default Gateway field. Enter the SonicWALL
WorkPort IP Address if NAT is enabled.
4. If configuring DHCP server for the HomePort, enter the gateway address used by HomePort
computers to access the Internet in the HomePort Default Gateway field. Enter the SonicWALL
HomePort IP Address if NAT is enabled.
5. Enter the domain name registered for your network in the Domain Name field. An example of a
domain name is "your-domain.com". If you do not have a domain name, leave this field blank.
6. Select Set DNS Servers using the SonicWALL Network settings to use the DNS servers that you
specified in the SonicWALL Network section.
If you want to use different DNS servers than the ones specified in the SonicWALL Network section,
then select Specify Manually. Enter your DNS Server addresses in the DNS Server 1, DNS Server 2,
and DNS Server 3 fields. The DNS servers are used by computers on your WorkPort to resolve
domain names to IP addresses. You only enter one DNS Server address, but multiple DNS entries
improve performance and reliability.
7. Enter your WINS Server address(es) in the WINS Server 1 and WINS Server 2 fields. WINS
Servers resolve Windows-based computer names to IP addresses. If you do not have a WINS
server, leave these fields blank.
8. Dynamic Ranges are the ranges of IP addresses dynamically assigned by the DHCP server. The
Dynamic Ranges should be in the same subnet as the SonicWALL WorkPort IP Address.
9. Enter the beginning IP address of your WorkPort IP address range in the Range Start field. Enter
the ending IP address in the Range End field. Select the Allow BootP clients to use range check
box if you want BootP clients to receive IP leases. Then click Update. When the SonicWALL has
been updated, a message confirming the update is displayed at the bottom of the browser
window. Continue this process until you have added all the desired dynamic ranges.
10. Enter the beginning IP address of your HomePort IP address range in the Range Start field. Enter
the ending IP address in the Range End field. Select the Allow BootP clients to use range check
box if you want BootP clients to receive IP leases. Then click Update. When the SonicWALL has
been updated, a message confirming the update is displayed at the bottom of the browser
window.Continue this process until you have added all the desired dynamic ranges.
