Proxy Routing

What is Proxy Routing?

The KNXnet/IP driver is unable to directly support the KNXnet/IP Routing Service. Proxy Routing is a mechanism we have introduced to provide the following:

  • To enable the KNXnet/IP driver to communicate with KNXnet/IP Router devices whose IP subnet differs from the Niagara Host IP subnet.
  • To allow the KNXnet/IP driver to communicate with multiple KNXnet/IP Router devices without using up a KNXnet/IP Tunnelling connection in each KNXnet/IP Router.

Proxy Routing relies on configuring a KNXnet/IP device in the Niagara Station using a KNXnet/IP Tunnelling connection to one KNXnet/IP Router device which has the same IP subnet address as the Niagara Host. The KNXnet/IP Router device’s filtering needs to be configured to allow it to route messages from the KNXnet/IP Tunnelling connection to other KNXnet/IP Router devices and vice-versa.

The other KNXnet/IP Router devices can then be configured as KNXnet/IP devices in the Niagara Station with their Connection Method property set to Proxy Routing and their Proxy Device address and other connection properties set to the KNXnet/IP device which was configured to use the KNXnet/IP Tunnelling connection described above.
