Add-In: Router Control
The first public release of the add-in Router Control has been released that allows you more control over your UPnP Internet gateway.
Its current main feature is the traffic graph as well as RouterControl online update check and schema upload. More features are to come in future updates, including:
Show and modify UPNP port forwards
Automatic (optional) forward of Home Server Homepage
Support for IP Internet connection (not only PPP)
German translation
Download traffic statistics (CSV)
Automatic (optional) error reporting
Router down notification
Notification on new port forwards
Although this functionality is partly provided by Windows Vista, it lacks features like traffic graphs and monitoring.
