PFSense with OpenVPN

[johnny26]

Hi,

I've enabled and configured openvpn together with PFSense.
However I'm having trouble connecting with my server.

I'm using a Windows 7 which has the OpenVPN client but unable to remote access the computers on the LAN network.

Details of my PFSense box
WAN IP: Static
LAN IP: 172.20.1.0/24
TUNNEL: 10.10.10.0/24

I'm having a output of:
"Warning: route gateway is not reachable on any active network adapters: 10.10.10.1"

Kindly advise.

Thanks.
