Configuring Firewall Dynamic Host Configuration Protocol

You can use the SonicWall® GMS to configure SonicWall appliances as DHCP servers. Dynamic Host Configuration Protocol (DHCP) enables network administrators to automate the assignment of IP addresses from a centralized DHCP server. This conserves IP addresses and make it easy for mobile users to move among different segments of the network without having to manually enter new IP addresses.

For SonicWall appliances running SonicOS 6.0 and newer, the SonicWall DHCP server options feature provides support for DHCP options, also known as vendor extensions, as defined primarily in RFCs 2131 and 2132. DHCP options allow you to specify additional DHCP parameters in the form of predefined, vendor-specific information that is stored in the options field of a DHCP message. When the DHCP message is sent to clients on the network, it provides vendor-specific configuration and service information. The SonicOS Administration Guide provides a list of DHCP options by RFC-assigned option number.

The SonicWall GMS provides a way to define DHCP options using RFC-defined option numbers, allowing you to easily create DHCP objects and object groups, and configure DHCP generic options for dynamic and static DHCP lease scopes. After 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.

Configuring DHCP Over VPN

DHCP over VPN enables clients of the SonicWall appliance to obtain IP addresses from a DHCP server at the other end of the VPN tunnel or a local DHCP server.

NOTE: This page has more options at the unit/appliance level.


Configuring Firewall Dynamic Host Configuration Protocol3

https://www.sonicwall.com/en-us/support/technical-documentation/sonicos-6-2-admin-guide-(1)

To configure DHCP over VPN:

1 Navigate to the DHCP > DHCP over VPN page.

2 Select from the following:

• To configure the SonicWall appliance to forward DHCP requests to local servers, select Central Gateway (default) from the Gateway list in the DHCP Relay Mode section and complete the following steps:

• To use the DHCP server built into the SonicWall appliance for some clients, select Use Internal DHCP Server. This option is not selected by default. When selected, the following two options become available. To use the internal DHCP server for:

• Global VPN clients, select For Global VPN Client. This option is not selected by default.

• Remote firewalls, select For Remote Firewall. This option is not selected by default.

• To configure the SonicWall appliance to:

• Send DHCP requests to specific DHCP servers, select Send DHCP requests to the server addresses listed below. This option is not selected by default. Then, enter the IP address of a DHCP server and click Add. The Modify Task description and Schedule dialog displays.

The address fields are updated.

Repeat these steps for each DHCP server that you want to add.

To delete a device, select the address and click Delete. A confirmation message displays.

Click OK.

• Broadcast DHCP requests, deselect Send DHCP requests to the server addresses listed below and leave the DHCP Servers field blank.

• To specify an optional DHCP relay agent, in the DHCP Relay Agent section, enter the IP address in the Relay IP Address field.

3 When you are finished, click Update. The Modify Task description and Schedule dialog displays.

The address fields are updated and the settings are changed for each selected SonicWall appliance.

To clear all settings and start over, click Reset.



Configuring SonicWall Appliances to Forward DHCP Requests Through a VPN TunnelTo configure the SonicWall appliance to forward DHCP requests through a VPN tunnel:


2 Select Remote Gateway from the Gateway list in the DHCP Relay Mode section. The options change.

3 Select the security association (SA) through which the DHCP server resides from Obtain using DHCP through this SA.

4 From DHCP lease bound to, select the interface to which the DHCP lease is bound.

5 To accept DHCP requests from bridged WLAN interfaces, select Accept DHCP Request from bridged WLAN interface.

6 Enter the IP address that is inserted by the SonicWall appliance as the IP address of the DHCP Relay Agent in the Relay IP Address field.

7 To manage this SonicWall appliance remotely through the VPN tunnel from behind the Central Gateway, enter the management IP address in the Remote Management IP Address field.

8 If you enable Block traffic through tunnel when IP spoof detected, the SonicWall blocks any traffic across the VPN tunnel that is spoofing an authenticated user’s IP address. If you have any static devices, however, you must ensure that the correct Ethernet address is entered for the device. This option is selected by default.



9 If the VPN tunnel is disrupted, temporary DHCP leases can be obtained from the local SonicWall appliance. After the tunnel is active, it stops issuing leases. To enable this option, select Obtain temporary lease from local DHCP server if tunnel is down.

10 When you enable the Obtain temporary lease from local DHCP server if tunnel is down option, clients are able to obtain IP addresses if the tunnel is unavailable. To ensure that clients use the remote DHCP server shortly after it becomes available, enter a short lease time in the Temporary Lease Time field. The default value is 2 minutes.

11 Click Update. The Modify Task Description and Schedule dialog displays.

Specifying Static IP Addresses on the LAN (WorkPort)To specify static IP addresses on the LAN (WorkPort):


2 In the LAN Device Configuration section, enter the IP address and Ethernet address in the LAN IP Address and Ethernet Address fields respectively.

3 Click Add. The Modify Task Description and Schedule dialog displays.

4 The address fields are updated.

5 Repeat Step 2 through Step 4 for each device that uses a static IP address.

6 To delete a device, select the address and click Delete. A confirmation message displays.

7 Click OK.

Specifying a Device Not Allowed to Obtain an IP Address Through the SATo specify a device that is NOT allowed to obtain an IP address through the SA:


2 Under LAN Devices Not Allowed to Obtain IP Through SA in the LAN Device Configuration section, enter its Ethernet Address.

3 Click Submit. The Modify Task Description and Schedule dialog displays.

4 The address fields are updated.

5 Repeat Step 2 through Step 4 for each device to be prohibited from obtaining an IP address through the SA.

6 To delete a device, select the address and click Delete. A confirmation message displays.

7 Click OK.

Configuring DHCP Settings

Topics:

• Configuring DHCP Settings for IPv4

• Configuring DHCP Settings for IPv6

Configuring DHCP Settings for IPv4To configure the DHCP server settings for IPv4:

1 Navigate to the DHCP > Settings page.

2 From View IP Version, select IPv4.

3 Select Enable DHCP Server.

4 To enable conflict detection, click Enable Conflict Detection.

5 To enable DHCP server persistence, click Enable DHCP Server Persistence.

When the DHCP Server is enabled, this setting allows the current state of the DHCP leases in the network to be periodically written to flash. Upon reboot, the system restores the previous DHCP server network DHCP IP allocation knowledge, based upon the IP/Lease times stored in flash.

When this option is enabled, the DHCP Server Persistence Monitoring Interval field becomes available.

• Enter a persistence monitoring interval (in minutes) in the DHCP Server Persistence Monitoring Interval field. This setting controls how often changes in the network are examined, and, if necessary, written to flash. The default time is 5 minutes.

6 Click Update when finished. The Modify Task Description and Schedule dialog displays.

7 Click Accept.

Configuring DHCP Settings for IPv6To configure the DHCP server settings for IPv6:

1 Navigate to the DHCP > Settings page.

2 From View IP Version, select IPv6. The available options depend on the IP version.

3 Select Enable DHCPv6 Server.

4 Click Update when finished. The Modify Task Description and Schedule dialog displays.

5 Click Accept.

IMPORTANT: Decreasing this setting to less than five minutes might reduce the overall read/write lifetime of the flash component.
