2.2 BUS ACCESS INTERFACE function  
The KNX/IP Router can be used to access the KNX BUS from any point of the LAN network; for this reason,  
it requires a second address (network address), as described in the Interface settings with ETS menu.  
ATTENTION! Remote access via NAT, without additional security measures, poses significant  
dangers. Port forwarding provides universal access to your local IP network and to your KNX  
system. Any Internet user can discover the open port on your static public IP address and can, for  
example, access your KNX network via the ETS software.  
Use NAT only temporarily for testing or diagnostic purposes. Afterwards, close the port again to avoid cyber  
attacks.  
If remote access is realized through NAT, it is highly recommended that you do not specify the default port  
3671 towards the Internet. Port 3671 is the official port for efcp - eFieldControl (EIBnet) registered by KNX  
Association. This port can easily be easily determined by unauthorized people. Please use a port in the non-  
reserved range between port 50000 and port 60000.  
Permanent remote access should be established only when protected! Remote access via Virtual Private  
Network (VPN) is recommended. The VPN feature is already integrated into most DSL routers.  
Setting a password for the ETS project can also help prevent malicious manipulation of devices.  
To always guarantee the correct level of security in KNX installations, consult the KNX-Security-Checklist-
