Mango V2 vpn server

Hi all can you help me with setting up the mango as a vpn server. I am behind a cable modem so my ip is dynamic. in the past i used and then set up dyndns for dynamic mapping from a secret website but with the mango i don’t see any of those options. How do you get the VPN server of the mango set up to be an always on home vpn server and map to a web address to with dynamic dns? thanks everyone

Upgrade to firmware 3.x and try DDNS
