I have a Draytek 2830N - Plus Router and wanting to setup VPN so I can access the Router when I'm out but having trouble figuring it out?

Thanks.

Very briefly: Assuming your are using a mobile device with built-in VPN dial-out
capability then you need to set up a VPN teleworker profile on the router and
then dial back to your router.... Use PPTP (simpler, less secure) to test
the theory...
