|If your ISP is not allowing you to connect to a VPN server then DynaDNS is not going to help you. Dyna DNS, as the name suggests, means Dynamic DNS and is used to connect to a remote server that has a dynamic IP address. Dyna DNS is implemented by the host, not by the client trying to connect. |
All it does is keep a URL synchronised with a dynamic IP address for a server of some kind. It wont do much more use as far as connecting goes than a conventional DNS. If you normally connect to your VPN via a static IP address then DynaDNS is superfluous.
Unless you yourself are hosting the VPN server it is of no use to you at all.
