What is the default external interface for SMA?

The default external interface for SonicWall Secure Mobile Access (SMA) is designated as X1. This interface is specifically configured to connect to external networks, such as the internet, facilitating remote access for users. In networking devices, external interfaces typically serve the purpose of managing incoming and outgoing data to and from the public network.

The designation X1 is standard across most SonicWall devices, making it an essential component in establishing WAN connectivity. This configuration allows administrators to utilize this interface for setting up secure mobile access connections, ensuring that users can securely connect to their resources from various locations. The other interfaces such as X0, X2, and X3 are generally used for different internal networking purposes or additional configurations.
