Configuring the General Settings for the WAN Interface

* 
TIP: Informational videos with interface configuration examples are available online. For example, see How to configure the SonicWall WAN / X1 Interface with PPPoE Connection. Additional videos are available at: https://support.sonicwall.com/videos-product-select
To configure General settings:
1
Click on the Edit icon in the Configure column for the Interface you want to configure. The Edit Interface dialog displays.
2
If you’re configuring an Unassigned Interface, select WAN from the Zone menu. If you selected the Default WAN Interface, WAN is already selected in the Zone menu.

3
Select one of the following WAN Network Addressing Mode from the Mode / IP Assignment menu. Depending on the option you choose from the IP Assignment menu, complete the corresponding fields that are displayed after selecting the option.
•
Static - configures the
•
SonicWall for a network that uses static IP addresses.
•
DHCP - configures the
•
SonicWall to request IP settings from a DHCP server on the Internet. NAT with DHCP Client is a typical network addressing mode for cable and DSL customers.
•
PPPoE - uses Point to Point Protocol over Ethernet (PPPoE) to connect to the Internet. If desktop software and a username and password is required by your ISP, select NAT with PPPoE. This protocol is typically found when using a DSL modem.
•
PPTP - uses PPTP (Point to Point Tunneling Protocol) to connect to a remote server. It supports older Microsoft Windows implementations requiring tunneling connectivity.
•
L2TP - uses IPsec to connect a L2TP (Layer 2 Tunneling Protocol) server and encrypts all data transmitted from the client to the server. However, it does not encrypt network traffic to other destinations.
•
Wire Mode (2-Port Wire) - is a deployment option where the
•
SonicWall appliance can be deployed as a “Bump in the Wire”. It provides a least-intrusive way to deploy the appliance in a network. Wire Mode is very well suited for deploying behind a pre-existing Stateful Packet Inspection (SPI) Firewall.Wire Mode is a simplified form of Layer 2 Bridge Mode. A Wire Mode interface does not take any IP address and it is typically configured as a bridge between a pair of interfaces. None of the packets received on a Wire Mode interface are destined to the firewall, but are only bridged to the other interface
•
Tap Mode (1-Port Tap) - can be configured between a pair of interfaces. All traffic received is bridged to the paired interface; in addition, the firewall does SPI and DPI processing of traffic. There is full Application Visibility, but no Application Control in Tap Mode
* 
NOTE: For Windows clients, L2TP is supported by Windows 2000 and Windows XP. If you are running other versions of Windows, you must use PPTP as your tunneling protocol.

If you want to enable remote management of the
5
SonicWall security appliance from this interface, select the supported management protocol(s): HTTP, HTTPS, SSH, Ping, SNMP, and/or SSH. You can also select HTTP for management traffic. However, bear in mind that HTTP traffic is less secure than HTTPS.

To allow access to the WAN interface for management from another zone on the same appliance, access rules must be created. See Allowing WAN Primary IP Access from the LAN Zone for more information.

6
If you want to allow selected users with limited management rights to log directly into the security appliance from this interface, select HTTP and/or HTTPS in User Login.
7
Check Add rule to enable redirect from HTTP to HTTPS, if you want an HTTP connection automatically redirected to a secure HTTPS connection to the
8
SonicWall security appliance management interface.

After completing the WAN configuration for your Network Addressing Mode, click OK.
