Resolution

Resolution for SonicOS 7.X

This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.

1. Navigate to Network| System | Interfaces| X1 .
2. Click  Configure.

3. Under IP assignment, choose PPPoE from the drop down menu.
   
   NOTE: The X1 Interface MTU is 1500 by default.
4. Enter the User name and User password given by the ISP. 
5. At the bottom of the page, you can choose Obtain IP address automatically if the ISP is leasing out IP addresses, or you can manually specify the IP address by choosing Specify IP Address and entering the IP Address given by the ISP.

6. Either check Obtain DNS server address automatically or manually specify it by choosing Specify DNS servers.

Protocol tab [Displays the acquired IP address, subnet mask, gateway address, and DNS server addresses]

1. Click Protocol tab.
2. View the settings for the acquired IP address, subnet mask, gateway address, and DNS server addresses.
3. Inactivity Disconnect—Specify how long [in minutes] the SonicWall appliance waits before disconnecting from the Internet, and select the checkbox.
4. Strictly use LCP echo packets for server keep-alive—This checkbox is enabled when the client recognizes that the server relies on Link Control Protocol [LCP] echo requests for keeping the PPPoE connection alive.
5. Reconnect the PPPoE client if the server does not send traffic for __ minutes—Select this checkbox and enter the number of minutes to wait without traffic before the connection is ended. When enabled, the PPPoE client monitors traffic from the server on the tunnel and disconnects when no traffic is seen for the specified time period.
6. Click OK .

How to test the connectivity

1. Navigate to Device | Diagnostics. Choose Ping .
2. Ping your ISP’s Default Gateway or any IP that is pingable on the Internet [e.g. 4.2.2.2].
3. Also try to ping a website [eg: www.google.com] to ensure that the DNS resolution is working.
