HA interface address behavior

terrzfor

We currently have a single SG310, which we want to extend towards an active/passive HA setup. We recently obtained a second SG310 (same revision). The documentation explains how to set up the HA pair, but does not explain in detail the behavior of the UTMs once they are in HA mode.

Will both UTMs still have their own individual IP addresses (for WebAdmin etc.)?

Will  the secondary UTM be a complete, inactive replica of the primary UTM? Or will the secondary UTM's WebAdmin interface still be accessible as an individual device?

I.e., if utm01 is 172.22.1.1 and utm02 is 172.22.1.2 before HA setup: Once the devices get integrated into an active/passive pair, will utm02 still be accessible via 172.22.1.2 or will it only be indirectly accessible through utm01's HA settings?

    Hi  

    Thank you for reaching out to the Community! 

    Once you configure HA Active/Passive, the only active unit can be accessed via WebAdmin. You can't access secondary UTM via WebAdmin. It is possible to SSH into the secondary UTM through primary UTM. 

    The secondary unit will have the complete configuration that is on the master unit. 

    For more information, please check out the High Availability section of the following document: Sophos UTM Administration Guide.

    Thanks,
