IPV6 Disconnected?

[prsrinivas]

@panks21

re your edgerouter script - I use the unifi usg3p behind the Airtel-provided Richerlink ONT on bridged mode. Also on a static IP.

When I try the equivalent script for the USG for PPPoE + IPV6, I am only able to get an IPV4 connection. am not sure what I am doing wrong. FWIW, I am also based in Dwarka, Delhi!

Thanks, Srinivas

@prsrinivas I hope you used unifi controller to provision.
I don't have USG with me as of now (gave it to a friend a year ago) but the config pushed by unifi controller should be good enough for IPv6. Infact my edgerouter config was mostly derived from USG config.

I am note sure but please check if you need to enable IPv6 on the controller level globally.

 

[prsrinivas]

@panks21 I have used the Controller settings as well as the config.json methods - nada on both trials. I will try doing a fresh install of the Controller and check again. Thanks for you comments!

For a short while a couple of months ago, the config.json method gave me ipv6 on the USG but no further. In any case, since I was (and am) using a static IPV4 did not bother too much.

 

[panks21]

@prsrinivas If you have static IPv4, IPv6 may not work for you even if you dial PPPoE. I believe they disable the IPv6 profile for static IPv4 customers in the backend. I got it re-enabled for me by some jugaad (don't ask me how)

 

[prsrinivas]

@panks21 Ah...so! Thanks again.
And apologies to OP for slightly hijacking the thread.

last 2 days the dilly-dally of airtel ipv6 has started again. now no matter what my airtel connection is always connecting (attempting to get ) ip6 but never gets it!
my experiments indicate that this is a router problem f670l not airtel problem

I turned off ipv6 in zte f670l and plugged in my D-Link router to lan4 which is bridged internally and enabled ip6 on dlink
now even if ipv6 is disabled in f670l my dlink is able to acquire it seamlessly as it is also front ending airtel wan
