IPV6-IPV4 tunneling

Question

I was assigned a task in which I need to implement an IPV6-IPV4 tunnel, it can be in Windows or Linux and then verify its operation with FPT or SHH service.

I'm thinking of doing it with an IPv6 tunnel broker like Hurricane Electric, but I'm not sure since there's not a lot of info around internet. Can someone advise me on a good way to do it? Thanks.

Answer 1

Here is a systemd service I wrote to create a tunnel. You'll have to replace the w's, x's, y's and z's with your own address values obtained for Hurricane Electric

he-ipv6.service
