@cosnomate As you say there is no setting for vpn. I know vpn has started by looking at the log when you first boot or restart the router.

You need to goto port forwarding then click application name and will see ipsec and pptp settings so you then goto computer setting for your ip address and once you have set everthing you save it.
Please note I have not used vpn on this router this is the best answer I can come up with. M
