Service Registry Settings (Windows CE 5.0)
The Service registry settings allow you to set up port mappings. You can configure a device to direct a specific band of incoming traffic through the specified Port to the InternalName server or some InternalPort. The incoming traffic can be TCP or UDP, as specified by Protocol.
This redirection of network traffic is different from the InternalExpostHost registry setting, which directs all incoming traffic to a specific IP address. The Service registry allows you to redirect only a specific band of traffic that is directed to a specific port. You can use both settings to filter traffic coming from the other side of the firewall.
Note The default registry values vary depending on which Catalog items are included in your OS design. For more information, see Default Registry Settings.
The following table shows the named values for the HKEY_LOCAL_MACHINE\Comm\ConnectionSharing\Servers\Service registry key that you can use to configure service-related items for ICS.
| Value : type | Description |
|---|---|
| InternalName : REG_SZ | Specifies the name of the server on the network to which the request should be sent.
This value can be any IP address. |
| InternalPort : REG_DWORD | Specifies the port number of the device listed in the InternalName subkey to which the request should be sent.
The valid range for this value is 0 to 0xFFFF. |
| IsEnabled : REG_DWORD | Default setting is zero (0).
