Release Notes: https://community.sophos.com/xg-firewall/b/blog/posts/xg-firewall-v18-mr4-is-now-available
For XG Appliances, running in Active-Passive, we can accelerate more performance with the new fastpath technology. You should see more performance throughput on XGs running in Active-Passive.
The HA Setup…
For testing purposes I migrated 2 XGs to 18-MR4 and I have the issue that one XG is in Sophos Central Firewall Manager still shown as MR3.
Sophos Central Firewall Manager:
A reboot dosn't resolve the issue.
Two firewalls or one Cluster? How long since the Update? Did you refresh the Cache of your browser?
It is a single filrewall. I've updated the XG yesterday in the morning (it is more than 24 hours ago, the reboot is also more the 24 hours ago). I cleared the browser cache and use a private session, still shown as MR3. I also tested it with another PC, which normaly does not use the Central Console but shown as MR3 too.
Still the old version shown in Central? Can you check on the XG Firmware images, that MR4 is actually loaded? Just to be sure?
