Vigor router supports LAN networks for NAT usage and Routing usage. The difference is that router translates LAN IP to WAN IP on to access network outside for NAT LAN, while LAN IP remains the same for Routing LAN.
By default, only NAT subnet can access remote VPN network via the VPN connection. In order to make routing LAN pass-through VPN, please enable ‘Pass Routing LAN to VPN’ in VPN and Remote Access>>LAN to LAN
There is also command available, please enter ‘vpn pass2nd on’ to enable the option.
In addiction to allowing routing LAN pass through VPN, we can also control packets to VPN remote network when VPN disconnects. When ‘Pass Packets to NAT when VPN disconnects’ is enabled, packets supposed to send over VPN will be sent to WAN when VPN disconnects; When it’s disabled, packets supposed to send over VPN will be dropped when VPN disconnects.
The command for this option is ‘vpn pass2nat on/off’
