Logic apps Ip Restriction

Question

I need to set my Azure app service's outbound IPs to my logic app IP restriction whitelist, so that nobody can call the logic app except through my api app. But the problem is that logic app restriction list only accepts IPs in range format x.x.x.x/x and I need to allow a set of 5 different IPs which is my API's app outbound IPs. App Service Ips

Answer 1

Looking at the documentation:

• Secure access in Azure Logic Apps

Logic App allows you to specify ip address + network mask.

/32 is a network mask of 255.255.255.255

So xxx.xxx.xxx.xxx/32 = ip address of xxx.xxx.xxx.xxx

if you use the /32 network mask, you will be able to add the specific ip addresses you want.

Answer 2

It seems that it's hard to assign a dedicated static outbound IP to a Logic App now.

Here is an issue that you could vote up it to promote the realization of this feature.
