Which protocols can Sophos XG Firewall use for SSL VPN?

The Sophos XG Firewall can utilize protocols designed for secure connections, and the correct choice emphasizes the use of OpenVPN and SSL. OpenVPN is a widely used VPN protocol known for its flexibility, security, and ability to traverse NAT (Network Address Translation) and firewalls. SSL (Secure Sockets Layer) is fundamental to establishing secure connections over the internet and is specifically tailored for VPN implementations on the Sophos XG Firewall.

These protocols enable users to create encrypted tunnels for secure remote access to their networks, ensuring data protection and confidentiality. The flexibility of these technologies allows administrators to configure the firewall to suit various business needs, from remote work to secure communication between sites.

On the other hand, the other choices involve protocols that are not primarily used or supported for SSL VPNs on the Sophos XG Firewall. For instance, PPTP and L2TP are older protocols typically associated with traditional VPN configurations but lack the strong security features provided by SSL and OpenVPN. Similarly, IPsec and GRE, while secure, are usually associated with different types of VPN configurations rather than the SSL VPN category. SSH is also not meant for VPN traffic in the same context, focusing instead on secure shell access for remote management rather than comprehensive VPN functionalities
