You can verify your connection using a remote client on the WAN.
To verify a User Connection from the Internet
From a WAN connection outside of your corporate network, launch a Web browser and enter the following:
https://<WAN_IP_address_of_gateway_device>
Select LocalDomain from the drop-down menu and click Login. The SonicWall Virtual Office screen displays in your Web browser.
You have now successfully set up your SMA appliance.
It is easier for remote users to access the SMA appliance using a fully qualified domain name (FQDN) rather than an IP address. It is recommended that you create a DNS record to allow for FQDN access to your SMA appliance. If you do not manage your own public DNS servers, contact your ISP for assistance.
