I am having trouble setting up port forwarding for some external devices. Since the router has only 1 LAN port, I have plugged in that LAN port a LAN switch and hooked 2 other devices on that LAN switch. I have set up the router for remote access (I have SIM card with a public static IP) and remote access for the router works, but there is no way to access the other two devices via port forwarding and nothing seems to be working.
I have set the router IP on 192.168.1.1 port 80
Device 1: 192.168.1.102 port 82
Device 2: 192.168.1.103 port 83
And as stated, it doesn't seem to be working, except router access.
