We have setup an XG cluster (Active/Passive) succesfully with the WAN interface configured using DHCP client because this is a requirement from our ISP. I read in KB 123174 (https://community.sophos.com/kb/en-us/123174) the following :
A High Availability (HA) cluster cannot be configured if any of the interfaces are dynamically configured using DHCP and PPPoE protocols.
This KB confuses me. Is DHCP on WAN-interface supported in HA or not? At the moment we are not experiencing problems with this setup.
Could anyone confirm me that this actually working or not?
