Unable to access management Interface from the LAN

08/19/2021 446 82634

DESCRIPTION:

SonicWall's Web management Interface can be accessed using HTTP and HTTPS using a Web browser. Both HTTP and HTTPS are enabled by default. The default port for HTTP is port 80 and HTTPS is port 443. However, if you configure another port for HTTP management, you must include the port number when you use the IP address to log into the SonicWall.

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.

   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. (For 6.5 OS Go to Manage | Firmware & Backups page)|(For 7.0 OS Go to Device | Settings | Firmware and settings 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.
