I got a bit of a problem lately. I want to access my home network from the internet using a VPN and DynDNS. For DynDNS I registered a free domain name at TwoDNS. My router is also setup to tell the DNS server its current IP address once in a while. But then I realized that the address shown at TwoDNS doesn't match the address my router has. This is due to the fact that I am living at a student residence that is connected to the network of our university.
So my local network probably lies behind multiple NAT-routers. Usually this would require a port forward but how if I am not in control of the routers. Maybe an external server with a constant connection to my home network will do the trick. What do you think?
Is there some kind of dynamic NAT?
Thanks in advance for any help
The solution is simple and there is one specific service to enable just what I described: LogMeIn Hamachi
