Hi,
I've configure commercial LTE modem with static IP in voxl flight. So my voxl flight has a constant IP. I've configure my PC (with QGroundControl) with commercial LTE modem with static IP as well.
PC connects to voxl-flight and ping  from my PC to voxl-flight works properly. But ping from voxl-flight with static IP to my PC doesn't work. Thanks in advance for your help.

@relevinsky What OS is your PC running? If Windows you'll most likely need to disable any firewalls  that are up. Windows' default firewall is pretty strict and won't allow traffic from random IPs.

@relevinsky have you done anything special to get a publicly routable IP on your PC?

Oops, Tom pointed out `commercial LTE modem with static IP as well`, never mind!
