Sophos XG Firewall experience - feedback wanted

I was hoping for those whom work with Sophos XG firewalls could provide some feedback.

We have a few in deployment, but on version 16 and 17 of their firmware have hit a number of issues this includes but not limited to;

• NAT rules not working (version 17)

• VPN connectivity issues - to other Sophos XG's (ver 16 to ver 17)

• A lot of HA issues - mainly the cluster dying after a failover. (both ver16 and ver17)

• Default administrator account locking out, no longer can use it after HA failure

I could go into a lot of detail about each of the issues if needed, and we've been intouch and working with Sophos on all of them. A lot of the issues were in the version 16 of firmware, we were assured these were all fixed in version 17, but we are still seeing various issues out in production.

I'd be greatful of feedback from those out there who either deploy or administer Sophos XG firewalls.
