If you want to have nice 2-3 or 5 outgoing IP’s for your app service, instead of 456 ones, you need just 5 simple steps.

1. Create Azure V-Net.
2. Create Subnet for your App Service.
3. Connect your app service with Subnet.
4. Create NAT Gateway and add IP addresses to it.
5. Go to V-Net subnet settings and assign NAT Gateway.

That’s it!
