Azure vwan - default subnetmasks
Hello
I have a question regarding the default subnetmasks assigned to the subnets in Vwan.
According to the Vwan FAQ documentation https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-faq#what-is-the-recommended-hub-address-space-during-hub-creation a /23 is recommended for the vnet. And it mentions that when using an NVA that the nva subnet will be a /28 or /27 (with multiple NVAs).
But what are the default subnetmasks for the ExpressRoute, site-to-site VPN, point-to-site VPN, Azure Firewall and Virtual hub Router subnets? a /27?
Is it also /27 when using a vwan hub address space of /24?
Is it correct to assume that when picking a /16 network address space for the vwan hub that the subnets will become /24?
Thank you for any extra information regarding this topic.
