Firewall support for Azure Relay is now in preview
Published date: 18 May, 2020
Azure Relay enables you to securely expose services that run in your corporate network to the public cloud. Azure Relay namespaces are accessible from the internet as long as requests are properly authenticated.
With new firewall support, now in preview, Azure Relay offers the ability to restrict connectivity to only well-known IP addresses or IPv4 addresses in Classless Inter-Domain Routing (CIDR) ranges for improved security.
