We need TIMUS VPN Gateway to be whitelisted. Some of our techs logging in to M365 to perform work while on the VPN and are being flagged as unexpected country logins from Singapore, because the tech is on the TIMUS Singapore Gateway. It would be very difficult to add expect rules for these individually because of the number of organizations under our account and different logins to perform work for different org's, so we need it whitelisted for the entire Account/Orgs. The gateway IPs appear to be static (but may change due to failover/redundancy, provider IP pool rotation, infrastructure scaling, etc.) Set to major because of escalation concerns from orgs under us.
