@bienicc:
LinxS,
Just make sure you put IP subnet of both sites into "IPv4 Remote network" fields (on both site), that I think you are done already. What you need is to pay attention to firewall rule at both sites, whether it allow to ping each other or not.
That resolved my issue, (after making sure I restarted my VPN service), Thank you for your help :D
Next I am going to implement SSL/TLS as it is more secure than shared key :)
