Change the 1 to 1 VPN routing
With this Add-in you can change the 1 to 1 VPN routing, to make additional private Networks reachable via the VPN connection. Important Variables:
- context.vars.centralVPN = true
- context.vars.remoteVPN = true
The following example expects the centralVPN Device to have an additional network, that the remoteVPN Device wants to reach over the existing VPN-Connection in the untagged (VLAN 1) Network.
