Symptom: The Appliance Is Reporting that the Security Appliance Is Already

Registered

If you get this message, the appliance is registered to another MySonicWALL account. If you have multiple

accounts, login to each of your accounts to determine the appliance registration account. If you no longer

know which account the appliance is registered to, contact SonicWALL technical support and ask for the

appliance serial number to be unregistered.

During peak periods, the appliance may be unable to connect to the MySonicWALL portal. Wait 15 minutes

before attempting to connect again.

VPN Troubleshooting

For a VPN tunnel to successfully negotiate, a number of settings must exactly match on both sides,

otherwise the tunnel fails to negotiate. The following is a list of settings to verify on both sides.

Verify that the VPN is Enabled on the SonicWALL Security Appliance

VPN is enabled by default but can be shut off inadvertently. Navigate to the VPN > Settings page and

verify that the checkbox next to Enable VPN is checked.

Settings section. Verify that the Enable checkbox to the right of your VPN Policy is also checked.

Fix Incorrect UFI Settings

If one side of the VPN tunnel is a SonicWALL security appliance with a WAN IP address that is obtained

dynamically, then Aggressive Mode must be used. For detailed information about configuring site-to-site

SonicWALL security appliances for VPN tunnels, refer to the Configuring VPNs Between SonicOS Standard and

SonicOS Enhanced technote document.
