Port forwarding in Azure for web application migration

Question

I have one on-prem web application that is working on domainname.com:7071 now we are migrating this app to Azure (Web App + Frontdoor). The client wants to include a port in URL, don't want to migrate without a port in URL. As per my knowledge, it is not possible in front-door. Is there any other way to forward port using any service?

@Krutik Shah ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you have a requirement that users should only be able to access your site on a custom Port 7071.

In that case, you have to use Application Gateway only.

• With v2, you may use any port in the range of 1 to 64999 except 22.
• See : App Gateway Listeners and Ports

More details on integration between App gateway and App Service :

• Application Gateway integration
• You must make sure there is a network path between App Service and App gateway either via
  • Internet
  • or Service EndPoint.

You can further use Azure App Service access restrictions to only allow traffic from App Gateway, this way no one can bypass the App Gateway to directly access App Service

Kindly let us know if this helps or you need further assistance on this issue.

Thanks,

Kapil
