How To: A deployed WCF Service in Windows Azure <=Communication/Accessing=> Local Intranet

My client has a public-facing Internet website (http-://www.-ABC123.-com/), and a local Intranet (http-://intranet.ABC123.-com/). However, The two sites are completely separated.

My client requested us to implement a specific functionality (WCF Service), and this service is actually supposed to communicate with both sites: their Internet and their Intranet, and perform some operations.

We have created the functionality (The WCF Service) and deployed it in Windows Azure, and its URL is: (http-://OurService.cloudapp.-net/OurService.svc).

The functionality (The WCF Service) is working perfectly with their Internet website, simply because all the URLs are public and accessible.

However, I am unable to connect our Azure WCF Service with the client's local Intranet. Therefore, Could you please help me out and tell me how can I make my WCF Service which is currently deployed in Windows Azure in the cloud communicate (Access and perform operation) in the client's local Intranet.

I would greatly appreciate your inputs !
you should look at configuring Virtual Networks so you can get the services to see each other.
I suggest you take a pause and analyse what's your problem first.

From where we can see, it's a connectivity issue. You want something in the cloud to access something on your intranet. It has nothing to do with it being WCF.

Roshan's suggestion is the easiest. You want slightly better, Virtual networks. You want some more dev work, Will's suggestion will work as well.

If you don't know how to setup firewalls/Virtual networks, ask your network guys.
