comment How to redirect MX records to origin domain name?
Thanks, right now I am testing this setup on gandi.net's DNS. AFAIK they use Bind 9 and when I try to put the name instead of @ I get an error that this already exists. I have read somewhere that by default, if nothing is specified, the MX of a zone is its origin so maybe that's why. But I'm not sure and can't find authoritative information on the subject. Right now it is working with @ but I would like to know if it's the way to go and if mail servers won't get confused.

comment OpenVPN on Docker
@MichaelHampton I'm interested in your comment. Would you care to expand on why it does not make sense to run OpenVPN in a Docker container? Or point to some resources about it? Containerizing it makes life a lot easier, so if you think it's not the right path I'd like to know more. Have you seen that project: github.com/kylemanna/docker-openvpn ? It seems interesting. Any comment is welcome.

comment Tunneling a public IP to a remote machine
Nice! I'm going to try that. Did you find a way to configure that: "without letting those clients use IPs to which they are not entitled"?

comment Build IPv6 over IPv4 tunnel between server and home network
Just to avoid confusion / distraction from the main question: I have access to a /48. And even if this were theoretical I would still be interested in knowing how this setup would work.

comment Build IPv6 over IPv4 tunnel between server and home network
@kasperd thanks for explaining the concept. I have tried the experiment you mentionned and the results confuse me. First I have tried to ping the address that is supposed to be mine and routed, the ::1 and the ping hung for a moment while tcpdump said: ICMP6, neighbor solicitation, who has x:x:x::1, length 32. And then my ip answered to the router: ICMP6, neighbor advertisement, tgt is x:x:x::1, length 32. And that's when the ping started to work. Then I tried with random addresses as you suggested and the same neighbor solicitation happened again. I'm not sure what to conclude here.

comment Build IPv6 over IPv4 tunnel between server and home network
@kasperd Thanks for the idea, I hope I don't have to get to that point! After playing a bit, it really looks like the server gets automatically configured with a /128 but the whole /64 is routed towards the server. So let's go with it.

comment Build IPv6 over IPv4 tunnel between server and home network
It looks like I can use the /64. I have a v6 IP that ends in ::1/128 and I have tried to add one in ::2/128 and I can ping it and connect through ssh to the server with that IP from the outside IPv6 world. I'm editing my question to reflect that.

comment Build IPv6 over IPv4 tunnel between server and home network
Indeed the /128 worries me. I have to get in touch with the ISP to understand exactly what they allocate (it is not clear in the contract nor admin panel). My previous ticket with them has been sitting opened for 2 days now so I don't expect a quick answer. But I am definitely interested in building this and if I have to get extra IPs I will consider it. So yes, please, if you have possible answers, go ahead!
