Dynamic DNS updating IP address that doesn't match router's IP
This may have been answered elsewhere but I couldn't find a similar question. I'm not talking about NAT here. I understand my devices have different IP addresses that are issued out by the router (...
Yes, there two layers of NAT, one by your router and one by the ISP. And, yes, that means that Dynamic DNS won't work. One way to work around that is to connect your home server to a VPN provider.
You would have to check with your ISP about the nature of your IPv6 address. If it's fairly stable, then there are Dynamic DNS providers out there that support IPv6.
Hey Ether,
Thanks a bunch for the reply. I sorta get the reason for NAT and I thought I at least understood it at my router level. It sounds sorta like there is just another level at my ISP... or something like that.
I also see what you're saying about it being unreachable. I think its working as you'd expect. What confused me was that when seeing my private address as the IP target in my noip configuration then my port was reachable - but you're right, it's only on my network.
So this makes more sense now. But does that mean that given my ISPs setup I can't use a dynamic dns service like No-IP?
My IPv6 address isn't static, right? Is there a way to configure a no-ip/like solution with IPv6? On No-IP i see a AAAA type but it requires be to give both a IPv4 and IPv6 address. I tried it and when the updates happen it still changes the IP target to my public IP which as we discussed can't be routed to my particular network/port.
Any ideas? Long story short, I'm just trying to set up a dynamic dns mapping to my home server. Thanks again!
