Im pretty new to LEDE and have a problem with Port Forwarding. My setup at the moment is that i have a Fibre Router supplied by my ISP which has DMZ setup to my LEDE Router. Any port i try to open does not work. The funny thing is that any Port opened with Upnp works perfectly. My firewall is set to default. Dont no what other information i must provided, but any help would be appreciated.
