I'm a whiz on IPv4, but I haven't really taken the time to learn IPv6 yet, so this might be a dumb question.
Long story short, due to some problems that were happening on a local system, I disabled IPv6 on my Asus as a test because I was seeing some strange DNS problems on a client.
Turns out this was actually the problem, and once I disabled it on the router my (one) system that was having this problem was ok.
After ensuring that everything else was working, I decided to re-enable IPv6 on the Asus, because it had all been working perfectly fine prior to the reconfiguration required on this one system.
I use the "Native" IPv6 setting, and let me also qualify that I have AT&T Fiber, and I use the wpa_supplicant on the Asus to bypass my AT&T modem and acquire the public IP directly on the Asus.
Prior to disabling IPv6 I went to one of the various IPv6 test sites (i.e. https://test-ipv6.com/) and it successfully passed all tests.
After re-enabling IPv6, it failed (i.e. couldn't detect IPv6).
I disabled and re-enabled IPv6 several times on my router. Each time it failed to report a success.
As a side-note, while my network seemed to get reconnected after every "disable", re-enabling would actually do a full router reboot. I'm not sure if this is normal.
While the "Native" setting was what had always worked for me before, I decided to just test setting it to "Passthrough". This didn't work, but when I then toggled from "Passthrough" back to "Native" everything seemed to work. What was (maybe?) interesting to me is that, as noted above, every time I went from "Disable" to "Native" my router would reboot. This time, when going from "Disabled" to "Passthrough" to "Native" I had no reboots (though the network connection was reset).
So I don't know what is going on with the above. I feel like I have had this issue before where IPv6 was set, but I wasn't able to pass the tests.
So my questions are:
1) Is there some type of delay before IPv6 address will be properly assigned and detected by these test sites? I was monitoring syslog and I didn't really see anything that would indicate it finally kicking in.
2) When I do an ifconfig to see my interface IPs, my eth0 interface shows my IPv6 public IP. The same showed on the main page as my WAN IP, and what is shown when I visit an IP test site. However, while the IP test sites now properly show a v6 address for me, I don't know where I can find that address on the router? The router must be aware of it's own IPv6 address, right? Where is it shown?
thanks
