I use a Bouygtel SIM card with only IPV6 access, APN ebouytgtel.com.
Strange problem, all windows devices connected have internet access and work well but all android connected haven't any internet access.
I have also a IP Camera connected on the 4G router, and P2P access dosn't work anymore. If i use internal setting show IP address, it return a NULL result.
Before I have a SFR SIM card with IPV4 / IPV6 access and i haven't all this problems.
Is somebody have a issue for this ?
