SonicOS 7 Getting Started Guide for NSsp 13700 and NSa Series

Testing and Troubleshooting Connectivity

If you have issues connecting to your firewall after setting it up, you can use the following tips to help diagnose the issue.

Testing Your Internet Connection

To test your Internet connection

  1. Reset your computer to use DHCP IP addressing and connect it to your LAN subnet or to the appliance X0 interface.
  2. Point your browser to the X0 IP address configured during initial setup (default: 192.168.168.168).
  3. Log into SonicOS using the configured credentials (default: admin/password).
  4. In a command prompt window, type: ping sonicwall.com. You should receive a reply.
  5. Open another browser tab or window and point it to https://www.sonicwall.com or another valid web site. If the site displays, you have correctly configured your appliance.

Troubleshooting your Internet Connection

To troubleshoot your Internet connection, try each of these suggestions:

  • Verify that the Local Area Connection settings on your management computer are set to use either DHCP or a static IP on the LAN subnet. Restart it or renew the DHCP address.
  • Verify that the WAN interface being used for Internet connectivity is not configured in Wire Mode or Tap Mode.
  • Restart your Internet router or modem to communicate with the DHCP client in SonicOS on the appliance.
  • Check all cable connections and IP addresses.

Troubleshooting Your MGMT Connection

If your MGMT connection doesn't seem to be working correctly, review the following suggestions:

  • Did you correctly enter the firewall management IP address beginning with “http://” or “https://” in your web browser?
  • Did you try restarting your management station while it is connected to the appliance?
  • Are the Local Area Connection settings on your computer set to a static IP address on the 192.168.1.0/24 subnet?
  • Is the Ethernet cable connected to your computer and to the MGMT port on your appliance, and are the connector clips properly seated in the ports?

Troubleshooting Your LAN Connection

If your LAN connection doesn't seem to be working correctly, review the following suggestions:

  • Did you correctly enter the IP address for the SonicWall X0 interface into your web browser, beginning with “http://” or “https://”?
  • Did you try restarting your management station while it is connected to the appliance?
  • Are the Local Area Connection settings on your computer set to one of the following:
    • Obtain an IP address automatically using DHCP
    • A static IP address on the default LAN subnet (192.168.168.0/24)
    • A static IP address on the configured LAN subnet, if you changed it during initial setup
  • Is the Ethernet cable connected to your computer and to the X0 (LAN) port on your appliance, and are the connector clips properly seated in the ports?

Using SafeMode

SafeMode is a limited web management interface that provides a way to upload firmware from your computer and reboot the appliance. The SafeMode feature allows you to recover quickly from uncertain configuration states with a simplified management interface that includes the same settings available on the System > Settings screen.

There is an E-CLI command safemode that restarts the firewall in SafeMode.

For more information about SafeMode, refer to SonicOS 7 Upgrade Guide.
