I noticed the section on VPN gateways has stated the following:
Note a /24 VPN CIDR block supports about 64 simultaneous VPN clients. This is because for each connected VPN client, VPN gateways reserves 3 virtual addresses. For larger number of clients per VPN gateway, consider making the VPN CIDR block to a /22 or /20 network.
Is 'reservation of 3 virtual addresses' by VPN gateways is due to the Load balancing that can be implemented across the gateways?
