Securing the VoIP feature in LANCOM routers against attacks from the WAN

Network components such as routers, which can be reached directly over the Internet (WAN), are under attack on a daily basis. LANCOM routers are no exception.

 

Attempts will be made to access the configuration of the device, or to monitor or manipulate the communications between the device and others connected to it. Similarly, there are attacks on the VoIP functionality in the router.

 

Attackers from the Internet attempt to initiate phone calls. These are often foreign connections or special services, which can lead to considerable expense to the operator of the router.

 

If telephony on a LANCOM router is set up using the Setup Wizard, the necessary settings are automatically put in place to protect against such attacks.

 

When configuring the VoIP functionality manually, please take into account the configuration steps described in the Knowledge Base document Securing the VoIP feature in LANCOM routers against attacks from the WAN.
