Sophos Firewall OS (SFOS) Update v17.5 - MR3 released

Patrizio - February 12, 2019

Sophos has released version 17.5 MR3 for the Sophos Firewall OS (SFOS). The new firmware can now be downloaded from the MySophos Portal .

In the next days the new firmware will also be available automatically via the WebAdmin of the firewall and can be installed with a simple click.*

Note: For more information on upgrading, please take a look at the following post: KBA 123285 Sophos Firewall: How to upgrade the firmware .

*Only those who have paid for Sophos Enhanced Support can benefit from this more convenient option. Sophos Enhanced Support is automatically included with each bundle (EnterpriseProtect, EnterpriseGuard, TotalProtect, FullGuard) or can be purchased separately.

What happened to MR2?

SFOS 17.5 MR2 was released as a silent release, exclusively for NSS Labs. NSS Labs has tested the XG firewall before MR3 has been released, so everyone can enjoy the new features and bugfixes.

APX Support

When the new APX series of Sophos access points was released in July 2018, it was only possible to use them with Sophos Central Wireless. Sophos announced back then that support for the XG firewall would follow in December 2018. Today, two months late, APX access points can be managed through the XG firewall. 🎉

We have tested the XG Firewall Support with our APX 740. Since we used to run it via Central, the link had to be cleared first. After that, the access point was displayed on the XG firewall immediately. The connection worked without any problems. 😅

If you have an XG firewall in use and need new access points, we recommend to consider only the APX series. The normal AP models are still available for SG firewalls with the UTM operating system.

Email Recipient verification using Active Directory

Since the UTM engine now also runs on the XG firewall, the last features are now gradually transferred to the XG. In SFOS v17.5.3 it is possible to do a receiver verification with Active Directory lookup. It is therefore checked in advance whether the mailbox or email address exists on the mail server before the email is sent.

Airgap Support

Airgap is a feature which has already been announced with SFOS 17.5. XG firewalls can now also be licensed and updated offline using this feature. The firmware could already be updated offline, but pattern updates are only possible with this firmware.

Bridge Interface - DHCP Client Support

Bridge interfaces can now receive IP4 and IP6 IP addresses and DNS information via DHCP.
