Port Usage for Mobile Applications

When setting up a firewall, enable the following ports:

ASP.NET State Service

If your mobile application requires the ASP.NET state server, configure it as follows:

Make sure ASP.NET state service is running on the remote server that will store session state information. This service is installed with ASP.NET and Visual Studio at the following location:
```
systemroot\Microsoft.NET\Framework\versionNumber\aspnet_state.exe 
```
In the application's Web.config file, modify the sessionState element as follows:
1. Set mode to "StateServer".
2. Set stateConnectionString to this:
```
stateConnectionString="tcpip=<computer_name>:42424"
```

If sensitive information will be included in view state, protect the connection. For details, see Securing Applications
