Possibility to whitelist INBOUND traffic from a FQDN instead of IP Adresses

Hello Everyone,

I want to whitelist inbound traffic from a FQDN instead of specifying IP addresses as the IP addresses are dynamic but the domain name would be static. Currently I don't see an option for whitelisting domain names in either NSG's or Azure Firewall. Could you please let me know how can we achieve this?

I would appreciate any help.

Thank you

Currently you cannot whitelist inbound traffic from FQDN on NSG or Azure Firewall.


You can create IP group and add your IP's to that group and use in Azure Firewall(Ref).


Also, you can provide the feedback in feedback.azure.com for NSG or Azure Firewall, or upvote to this existing feature request of this ask here.

In NSG, inbound using FQDN is not yet supported.

In Firewall it is supported, ref this document for more details.

In Firewall I still see this for Outbound traffic, does it also support Inbound traffic?
