CP as passive subscriber of VPN connections
Setting permission for VPN connection establishment with passive subscribers
If the CP is connected to another VPN subscriber via a gateway, you need to set the
permission for VPN connection establishment to "Responder".
This is the case in the following typical configuration:
VPN subscriber (active) ⇔ gateway (dyn. IP address) ⇔ Internet ⇔ gateway (fixed IP
address) ⇔ CP (passive)
Configure the permission for VPN connection establishment for the CP as a passive
subscriber as follows:
1. In STEP 7, go to the devices and network view.
2. Select the CP.
3. Open the parameter group "VPN“ in the local security settings.
4. For each VPN connection with the CP as a passive VPN subscriber, change the default
setting "Initiator/Responder" to the setting "Responder".
