16.3 Universal Plug-and-Play (UPnP)

WinRoute supports UPnP protocol (Universal Plug-and-Play). This protocol enables client applications (i.e. Microsoft MSN Messenger) to detect the firewall and make a request for mapping of appropriate ports from the Internet for the particular host in the local net- work. Such mapping is always temporary — it is either applied until ports are released by the application (using UPnP reports) or until expiration of the timeout.

The required port must not collide with any existing mapped port or any traffic rule allowing access to the firewall from the Internet. Otherwise, the UPnP port mapping request will be denied.

Configuration of the UPnP support

To configure UPnP go to the Security Settings folder in Configuration Advanced Op- tions.

Figure 16.4 IPnP settings (the Security Settings tab under Configuration / Advanced Options)

Enable UPnP

This option enables UPnP.

Warning: If WinRoute is running on the Windows XP operating system, check whether the following system services are not running before you start the UPnP function:

SSDP Discovery Service

Universal Plug and Play Device Host

If any of these services is running, close it and deny its automatic startup. In WinRoute these services cannot be used together with UPnP.

Note: The WinRoute installation program detects the services and offers their stop- ping and denial.

Port mapping timeout

For security reasons, ports required by applications are mapped for a certain time period only. Mapping is closed automatically on demand of the application or when the timeout (in seconds) expires.
