Windows 11 and EE 5G Data SIM cellular network VPN issue

Fred106 · ‎29-09-2023

Hello,

I have new Dell laptop Windows 11 direct connect to a cellular network (EE 5G Data SIM card). That make me can't establish VPN connection (L2TP). Even ping the VPN server IP address still no result.

Other issue: OpenVPN is work in this laptop and cellular but just can browse some website only ( Google and Microsoft) when VPN connected.

There is nothing problem when I use WiFi network. Is this EE 5G IPv6 issue?

Hi @Fred106,

Welcome to the EE Community. 🙂

Are both your VPN clients up to date and set to dualstack mode?

Both of 2 clients are up to date and dualstack mode is enabled.

Hi @Fred106

Have you been in touch with the VPN provider to see if they can offer any support?

@Fred106 : It might be an EE IPv6 issue. EE has introduced IPv6 on its mobile network, but it doesn't fall-back to IPv4 nicely. Can you change the Profile/APN on your mobile router to APN Protocol = IPv4 only?

I tried your solution today but can't access internet when APN just select IPv4 only.
