add support for ipv6 - Githubissues

It is true that IPv6 discourages NAT. But there are some special situations that IPv6 NAT is necessary. For example:

Your cloud service provider only allocates IPv6 addresses to you and you want your VMs accessible from the Internet.
In mainland China, IPv6 network is less congested and has fewer censorship than IPv4 network.
To prompt IPv6, CERNET (China Education and Research Network) provides FREE IPv6 access while IPv4 needs a payment.

In such situations, users may prefer IPv6 over IPv4.

I have made an issue but it seems no one cares IPv6. So I forked this repo and add my support for IPv6 NAT.

I have done some testing on my computer. It works well and solves my problem. Hope the kindly author would review my pull request.
