Network
The phone is integrated into a local network and receives an IP address through which the integrated web server can also be reached for configuration.
These protocols can be set up for the device:
•IPv4
•IPv6
•VLAN
•VPN
•LLDP
VLAN
A VLAN (Virtual Local Area Network) is a logical network within a physical network.
Requirements for configuration
•VLAN is provided in the network
VPN
To be able to securely connect remote devices with each other (e.g. telephones as external extensions on a PBX), you need a VPN connection between the devices.
A VPN is a logical private network on a publicly accessible infrastructure. Only communications partners that are on this private network can exchange data and information. Data is exchanged via the VPN tunnel, where the tunnel acts as the envelope in which the data is transported.
Requirement for configuration
•Each end point must support the specific tunnelling protocol that is being used.
•You need to know the access data required to configure a VPN connection.
A function key can be set up to easily switch the VPN connection on and off as needed.
LLDP
IP phones use LLDP to collect and query device-specific information from devices that are directly connected in the network. This automatically updates the VLAN configurations contained in the LLDP packages. The VLAN configurations are uploaded from the switch to the IP phone. An IP phone can therefore be connected to any LLDP-enabled switch, receive its VLAN configurations (internal port) and then start communications via the VLAN (plug and play networks). To do this, the IP phone sends its device information using the LLDP-MED software upgrade.
Requirement for use
•Devices that are directly connected in the network must also use LLDP.
Configuration
To set up the network connection for the first time, consult the phone's instructions.
Note: Some network settings relating to telephony can be found across identities in the topology area of the network settings (e.g. LLDP, jitter buffer, STUN server). Others can be set separately for each identity (e.g. NAT, outbound proxy, certificates).
Note: The VPN can merely be enabled/disabled on the phone. It can only be configured in the web interface or by provisioning.

Auerswald DokuWiki.
Note: An example VPN configuration for a FRITZ!box is also shown in the Auerswald DokuWiki. This configuration cannot be applied to VPN connections that are to be set up in a company environment.
