App services external connection

Question

I have an application in my app services that must communicate with a server that is outside the network to validate the license, how can I make this communication effective or confusing since I configure the IP and ports in the security group in subscription house and nothing

Hello Manuel Escalona,

I understand that you want to enable the communication (whitelist) from the App service to a Server on other network not Azure. In that case you have two options:

• In the network of the server you need to permit the Outbound addresses of the app service for incomming communication (https://learn.microsoft.com/en-us/azure/app-service/overview-inbound-outbound-ips#when-outbound-ips-change)
• Using App service virtual network Integration it's required some additional Azure resource such as vnets, nat gateway so you can control outbound traffic with network security groups to a limited extent, such as the target IP address, port, and protocol. Afther this configuration you need to add the public outbound IP in the network of this external server.(https://learn.microsoft.com/en-us/azure/app-service/overview-vnet-integration?source=recommendations / https://techcommunity.microsoft.com/t5/apps-on-azure-blog/how-to-fix-outbound-ips-for-app-service/ba-p/2320612)
