Everything was working fine during months. I had a new box from my internet provider and now. Monflo is not working. Firewall nat dmz upnp all is the same as the old one. But I can't connect correctly from any other device pc/mobil wifi android when they are not in my home network. Please help.

Nothing with Mobil data provider. I have the same issu but it was completely working fine during 3 months and all I have changed is my box/rooter. I let you now that even with same rules then before or when port are opened it is still not working anymore. There must be something to fix it. Sometimes...
