How can the Sophos XG Firewall support remote users?

The Sophos XG Firewall supports remote users primarily by enabling Remote Access VPN. This feature allows remote users to securely connect to the organization's network over the internet. The Remote Access VPN creates an encrypted tunnel between the user's device and the corporate network, ensuring that data transmitted is secure and private. This capability is essential for employees who need to access corporate resources from outside the office, providing a reliable and secure connection to applications, files, and other network services as if they were physically present in the office.

In contrast, other options do not directly facilitate remote access in the same way. Dynamic DNS service supports users in maintaining a consistent domain name when IP addresses change, which aids in locating remote resources but does not directly connect users. A built-in VoIP service may enhance communication but does not provide secure access to the network. Restricting access to known IP addresses is a security measure that allows connections only from predefined locations, which can inadvertently limit remote user access instead of facilitating it. Hence, enabling Remote Access VPN stands out as the most effective and relevant feature for supporting remote users on the Sophos XG Firewall.
