Unable to access management Interface from the LAN

03/26/2020 370 78817

DESCRIPTION:

RESOLUTION:

You log into the SonicWall management Interface using https://IP Address where the IP address is the SonicWall LAN IP address.

EXAMPLE: If the LAN IP address of your SonicWall appliance is 192.168.168.1, you can log into it by typing https://192.168.168.1.

EXAMPLE: If you configure the port to be 76, then you must enter http://192.168.168.1:76 into the Web browser.

NOTE: Modifying default HTTP and HTTPS management rules may render the SonicWall's Web management Interface inaccessible. You need to use the CLI to restore the default rules.

• Web management settings can be found under Manage | System Setup | Appliance | Base Settings.
  
  
  
• Locate the management access rule by navigating to Manage | Policies | Rules | Access Rules.

1. Physical Inspection.
   Learn more www.sonicwall.com/support/knowledge-base/170507123738054.
   If you press the Reset Button the SonicWall security appliance will boot in Safe Mode.
2. Accessing SonicWall management page from the network.
   
   • Ensure that the computer and the SonicWall device are in the same subnet.
   • The Default Gateway of the computer should always be the SonicWall device’s LAN IP address.
   • Ping the current IP address of the SonicWall.
   • Telnet to default HTTP and HTTPS management ports (check if ports were modified). 
     

     EXAMPLE: 

          HTTP : Use telnet 192.168.110.1 80

          HTTPS: Use telnet 192.168.110.1 443

   • If you have modified the default management port, then use the appropriate ports.
   • Use latest Internet Explorer browser to access the SonicWall management page.
   • Try to access the SonicWall management page using another windows computer.
     
     
3. Verify Internet Explorer Settings.
   
   • Always use the latest Internet Explorer browser to access the SonicWall management page.
   • Enable ActiveX Settings.
   • Delete cookies, delete history, delete all offline content in the Temporary Internet Files area.
   • Disable Proxy server settings in the IE browser.
   • Under Internet Options | General | Settings, select Every visit to the page and try again.
   • Reset IE browser settings to Restore Defaults and try again.
     
     
4. Connect a computer directly to the SonicWall device LAN Port.
   
   • Use the Cross-Over cable to connect a windows computer directly to the LAN port of the SonicWall.
   • Run the SetupTool to discover the SonicWall's IP address.
   • Change the IP address of the computer to be on the same subnet and try to access the SonicWall management page with the current IP address of the SonicWall.
   • The Default Gateway of the computer should always be the SonicWall device’s LAN IP address.
   • Verify IE browser settings.
   • Follow the last four steps mentioned in “Accessing SonicWall management interface from the network” section.
     
     
5. LAN computers can access the Internet but cannot access SonicWall management page.
   
   • Verify IE browser settings.
   • Try using another windows PC.
   • Ensure HTTP and HTTPS management ports are not modified.
   • Ensure HTTP and HTTPS management rules are not modified.
   • If you have enabled HTTPS management through WAN, try accessing from the WAN side.
   • Telnet to default HTTP and HTTPS (80 and 443 respectively) management ports (check if ports were modified).
   • Power Cycle the SonicWall.
   • Reset SonicWall management port to defaults through Command Line Interface (CLI).
     
     
6. Cannot access SonicWall management page after Firmware Upgrade.
   • Always export the Preference file before upgrading the firmware. (Go to Manage | Firmware & Backups page)
   • Ensure you have selected the option “Uploaded firmware” while upgrading the firmware. By using this option, all of the previous configurations will be saved.
   • While firmware upgrade is in process, ensure that rebooting or lockup has not occurred.
   • Run the SetupTool to discover the SonicWall's IP address.
   • Try to ping the SonicWall’s LAN interface IP and the upstream device’s IP.
   • Telnet to HTTP and HTTPS management ports.
   • Use SonicOS Command-Line Interface (CLI) guide (console port) and use appropriate commands to reset the settings.
   • Power Cycle the SonicWall.
   • Verify that the Link, Activities, Tool or Alarm light status are good and are not dim.
   • Verify the power cable is good and not loose. For external power supplies, try one from a similar SonicWall (5V DC, 2.4A Rating).
   • Try using another network cable or port. You can also self test by connecting a cross-over cable (red cable from SonicWall) between the LAN and WAN ports. The link light and activity light will become active if they are good.
