PORT FORWARDING ON THE HUAWEI B315 4G ROUTER
The video below shows where the settings are to configure port forwardin on the B315 4G Router. This assumes that you have already decided on a method to remotely access your router for exapmple using a Fixed IP SIM card.
port forwarding will not work unless you are using a compatible mobile network service that enables you to remotely access your router - many standard mobile data SIM card providers use CGNAT so your 4G router only receives a private IP address so cannot be accessed and also means that services like DDNS / DYNDNS will not work and also port forwarding will not work so please check with your mobile provider whether your connection receives a PUBLIC or Fixed and accessible IP address to enable remote access to the router otherwise port forwarding will not work.
