I currently run an OpenVPN Server via a home network connection that has a single, public, dynamic IPv4 address.
My provider (AT&T U-Verse) will apparently soon switch to a large-scale NAT and only assign me a private IP address anymore, so as it stands I will be unable to reach my home VPN while on the road.
In the short term, I could change providers, but I expect all other providers to run out of public IPv4 IPs soon enough and implement a similar system.
Thus, I am pondering my options to traverse the LSN barrier:
- is there any way that I am missing, for me to reach the box behind the LSN?
- until the ISP assigns me an IPv6 address: can I set up an IPv6 tunnel and reach my VPN server on IPv6?
Assuming I somehow get a native or tunneled IPv6 connection to my home router (but due to LSN, not an IPv4 connection):
- what can I do to be able to reach my home network, even if I am located in an IPv4-only network somewhere on the planet (coffee shop, for example)?
Sorry for the many questions, but I am a bit lost here and could use some help narrowing down the problem space.
