I've added a router to a LAN with multiple devices that perform metering and output data on a web-server. My end-goal is to access this data remotely. The devices each have assigned IP addresses and I have forwarded their ports from the router. When I access these devices by ethernet connection to the LAN I am able to get to their web pages but when I try to access the websites remotely via IP and port I cannot load their web servers. I can succesfully ping to the devices remotely but cannot access anything else. Is it a matter of not all ports for the devices being open / what other problems could be present?
