Guys,

I need to address possible extreme slow connection tunneling speed when locking to my home VPN network via cellular network: not more than 500kBs download and not even 30kBps in upload.

My home adsl speed is not so high meaning I have 7MB max download and 1MB in upload, so I need to know whether is normal given that or not.

To do this I would need to tweak my openvpn configuration file both server and client side to do some tests, but I cannot figure out how to do this on my router as there's an export button only with no chance to make changes in openvpn config before exporting. 

Any help is appreciated. 

Thanks
