Hello Everyone,
We have a mail server deployed on esxi which is protected by mail protection of a virtual sophos XG on same esxi. we are considering to deploy another XG box an configuring HA with active/active mode. I've searched sophos community and found that several people have issues with deploying XG HA on virtual environment and in several cases problem resolved with allowing mac address change on virtual switch that seems logical since configuring HA creates virtual mac on interfaces and so mac address change should be enabled. Idecided to test XG HA on VMware environment for myself and finally succeeded to configure 2 XG box in active/active HA after enabling mac address change on my virtual switch configuration.
My concern is that there is no official sophos guide about configuring HA on virtual environment. Also in none of official documents about HA, there is no reference about HA support on virtual environment. So first of all I need someone from sophos support team on community confirm that deploying xg with HA on VMware environment is officially supported. Also in my tests, I found with only one client on lan side of XG active/active cluster, all traffic is passed through primary device and on auxiliary device there is no connection from my client. I want to know that which method XG uses to load balance traffic on active/active cluster and is there an option to change load balancing method?
Sincerely,
Farshid
