HA link zone?

Quallensaft 4 hours ago

What's "best practice" regarding HA link network?

- at the moment my HA link network (physical port / peer2peer) is zone DMZ -> not cool because SSH access for DMZ zone must be activated or HA will not work anymore -> SSH access from DMZ zone on all HA firewalls possible?

https://docs.sophos.com/nsg/sophos-firewall/20.0/Help/en-us/webhelp/onlinehelp/HighAvailablityStartupGuide/HAConfiguration/HowToArticles/HAHowToActivePassive/index.html

When switching to zone "none" do I also have to configure anything regaring SSH (needed for HA sync)? HA sync need FW rules?

You can use your own Zone, for example, create a Zone called HA and use the same settings (HTTPS and SSH). Then move the zone of HA Link to this Zone.

You need to break up the HA first, to do this.
But yes, you should be careful with the usage of DMZ in other zones as well, as it enables per default SSH as well.
