Hello,

I have the MR200 4G router with a double NAT issue.

The router is on a remote location with a device with a web interface witch I need to control remotely.

Because off the double NAT the OpenVPN tunnel isn't working even with NO-IP service.

My ISP won't forward any ports to my ip to let the VPN work.

Is there any device I can put in the remote network to let me access my device?

I know a pc with Teamviewer solves this but I'm looking for a cheaper solution.

I know this device Gira S1 (https://www.gira.com/en/en/products/smart-home/gira-s1#) can solve this, it is a device connected to a cloud portal and with this you can access devices their webinterface in the same network as the S1 trough the webportal, but this is for smart houses with KNX systems and is also an expensive solution. 

Does anyone have an idea how to solve this?

Thank you

Ruben
