tunnel

Here is my problem. I have a server A that has two IP addresses. One public IPv4 and one IPv6.

Server B has only one IPv6 address.

I want to host most of my services on server B (because I have more disk space on it, I can control it better) but I need the IPv4 of the server A. I would like to set up a 4in6 tunnel (RFC 2473) between A and B so that I can transfer the traffic from the IPv4 address in A to B.

If needed, I can request another IPv4 address on the server A, but I'd prefer not to.

My question is: which software use to do the 4in6 tunnelling? I suppose OpenVPN can do the thing, but is there any implementation of the 4in6 protocol on Linux?

A little more challenging: the IPv4 address comes from a venet interface, which cannot be bridged. How could I transfer ownership of this address I don't use on server A to the server B?

Thank you

IPv6 is extremely important for the long-term health of the Internet. But is your Internet service provider providing IPv6 connectivity yet? Does your home network support it?
