Azure Administration Portal
Let’s begin by navigating to the App Service (or a Staging Slot) and click on on Configure Entry Restrictions hyperlink which is obtainable within the Networking Blade as proven under.
You’ll be taken to the Entry Restrictions blade as proven under.
Under are the parts of the Entry Restrictions blade highlighted within the above screenshot.
- The primary tab reveals all of the entry restrictions utilized the Azure app service.

- Add Rule button can be utilized create a brand new rule to be utilized for the entry restrictions of the app service.
- And at last you possibly can view all the present entry restrictions which are out there for the present app service.
Let’s now add new entry restriction rule on the app service by clicking on the Add Rule button.
Within the Add Entry Restriction blade, you possibly can present the next values to create a brand new Enable/Deny rule.
|Identify||The identify of the rule.|
|Motion||Enable – deciding on this selection will let the person entry the App Service from the given IP Handle (within the IP Handle Block) Deny – deciding on this selection will NOT let the person entry the App Service from the given IP Handle (within the IP Handle Block)|
|Precedence||The precedence given for this rule.|
|Sort||Choose IPV4 (extra on this under)|
|IP Handle Block||Present the IP Handle Vary. If you need to say just one IP Handle then present one thing on this format 188.8.131.52/32|
This text focuses on the sort IPV4. The method for IPv6 can also be the identical. Nonetheless, the Entry Restrictions function permits us to manage the entry utilizing the under varieties.
You’ll be able to go away the remainder of the fields as they don’t seem to be necessary and click on on the Add Rule button so as to add the rule. As soon as the rule is added. You discover the under two adjustments.

When you add a brand new rule (both Enable or Deny) a Deny All rule (proven within the above display) will probably be created and nobody will probably be allowed to entry the rule besides the Enable guidelines ones that are allowed explicitly utilizing the Entry Restriction blade.
That’s it. Now we have added an Enable rule for a Single IP Handle to entry the Azure App Service. Customers from different IP Addresses will be unable to entry the Azure App Service. In the event that they attempt to entry then they’d obtain an error with the message “Error 403 Forbidden – The online app your have tried to succeed in has blocked your entry” as proven under.
On this article, we have now realized the best way to manually enable/deny entry to a single IP Handle utilizing the Azure Administration Portal. Within the subsequent article, we are going to discover ways to carry out Bulk insertion of the IP Addresses utilizing PowerShell.
Hope it helps. Comfortable studying.
