I've set up SSID2 on my Vigor 2860n+ so users who connect to that get added to VLAN1 which is then configured for subnet LAN2. I now want to setup a VPN connection on the router so any users connected to VLAN1 will get routed through the VPN rather than directly to the internet.

The VPN is configured and connects fine, but it appears that devices connected to VLAN0 and VLAN1 are both going via the VPN. I only want devices on VLAN1 to route through the VPN connection.

Is this actually possible, and can anyone help me with the last few steps please.

Thanks

Are you using the route option in the VPN to do it or are you using a policy route ? Use the latter because that should work with the source IP set as LAN2's IP range
