X750 v2 cannot create a VPN Server over 4G


I bought a X750v2 to leave in a remote location to access via 4G to the LAN devices.

My plan was to setup an openVPN server on the equipment, but I don’t know why, I can’t connect.
Also tried the Wireguard but with no success.

I noticed that the IP address on the Internet zone (4G) is different from the myipaddress.com like you can see in the pictures attached.

Could this be the cause of my problem connection with VPN server?

I tried to forward the port of the x750 webserver to access it from the internet (just a test) but I cannot access also !

I have tried with the ovpn edited with the 2 ip addresses but still the same problem…

Any ideas ?

Thats the log of the windows ovpn client when I try to connect.

I also tried to open the port 1194 in the Firewall settings (I don’t know if it is necessary)

IP address 100.98.46.xxx is a Private network IP address that is assigned by your 4G service provider. In turn, I believe your provider applies NAT to map it to the Public IP address 46.50.113.xxx. In this case, I don’t think you can set up a VPN server that will be accessible from the Internet, but you can check with the provider about getting a dedicated Public IP address.

The client log shows trying to connect to Where did this IP address come from?

I do not work for and I do not have formal association with GL.iNet



That last printscreen was taken in other day !

The Public IP changed from 46.50.113.xxx to 31.22.150.xxx !

Is there any difference from an access from 4G or Fiber ?

Is there any way of bypass that limitation ?

Thank you for your feedback

You cannot use as server if you don’t have a public IP.


  1. Ask your carrier send you a fixed IP SIM card. You need to pay for that of course.
  2. Use www.astrorelay.com to relay your vpn service.

Is Astrorelay similar to Zerotier ?

No. Zero tier is for creating networks.
Astrorelay is socket relay.
