14.5.3 Inspect VPN rules
VPN rules represent a combination of various pieces of information and they
are not directly defined in a LANCOM device; instead, they are compiled from
a variety of sources. This is why it is not possible to inspect the VPN rules with
LANconfig or any other configuration tool.
Information about the current VPN rules in the device can be retrieved with
the Telnet console. Start a Telnet connection to the VPN gateway and enter
the command show vpn in the console:
The output informs you of the network relationships that are relevant to VPN
connections to other networks.
In this example, the local network at a branch office (network 192.168.2.0,
netmask 255.255.255.0) is connected to the network at the headquarters
(network 10.0.0.0, netmask 255.255.255.0). The public IP address of the local
gateway is 80.146.81.251, and that of the remote VPN gateway is
217.213.77.120.
Entering “any:0” displays the protocols and ports that can be used
over the connection.

information displayed here covers network relationships and also the
parameters that are relevant to security, such as IKE and IPSec
proposals.
