Sophos SFOS update – new features in v18.0.5
With the Sophos Firewall release 18.0.5 or also called v18 MR5, Sophos brings again new features besides bug fixes.
IPsec performance improvements
With the MR3 release , SSL VPN performance was tweaked so that more SSL VPN connections were suddenly possible with the same hardware. With MR5, more IPsec connections are now possible via the Sophos Connect client.

WAF and SSL VPN with port 443
The Web Application Firewall is one of the rather rarely used modules of the Sophos Firewall. The problem was often that applications were secured with port 443 (HTTPS). Unfortunately, this meant that it was no longer possible to use the same port for the SSL VPN. With MR5, the WAF and SSL VPN can now be used together on port 443.
Azure Active Directory
This new feature will also please some of our customers. Sophos Firewall can now be used with Azure Active Directory, without Microsoft’s expensive “Azure Active Directory Domain Services”. How this works is beautifully explained in Sophos’s KB post: Sophos XG Firewall: Integrate XG Firewall with Azure AD
