I’ve switched ISP.
The new ISP working with NAT on IPv4, so my yunohost isn’t available anymore.
But, the new ISP is supporting IPv6, I’ve enabled updated the dyndns and have successfully accessed yunohost.
The issue is my mobile operator, who isn’t supporting IPv6 as all of the AP I’ve tried.
Possible solutions I’ve found:
Free IPv6 tunnel: https://tunnelbroker.net/ (But haven’t found free android client)
Free VPN (also didn’t found any)
(limited bandwidht, configuration)
Except switching ISP is there reliable solution to my problem?
