  • Your ISP might make you go through another layer of NAT. Can you find the WAN IP address of your router and compare it to your public IP address from a website such as ipinfo.io ?

    If they do not match, you’re probably out of luck and will need to forward your port from an actually public IP in order to achieve what you want

    More details : CGNAT (Carrier Grade Network Address Translation) is basically a second router between your router and the public internet. This second router is configured in the same way as your personal one, the main difference being that your ISP fully manages it. From the viewpoint of this second router, your WAN IP is a private IP, and you share one actual public IP with several other customers (the same way all devices on you LAN share one single WAN IP)

    Performing port forwarding from the public internet to your LAN, when behind a CGNAT, would require you to be able to configure a forwarding rule in the ISP’s NAT, which you usually cannot do.



  • KOReader is by far better than the crappy stock firmware from Kobo. While the interface is not the prettiest, it still has a lot of advantages :

    • it adds the ability to browse the filesystem (how do people use an e-reader without folders ?)
    • loading medium to large PDFs takes ages in kobo’s stock UI, while it’s almost instant in koreader
    • there are a bunch of plugins you can add to koreader

    While I really hate Kobo’s stock UI, I still recommend getting one if you like truly owning your hardware. It’s really easy to enable ssh access and then it’s just regular Linux. It’s even possible to run an X server and launch Linux graphical apps on the e-ink display (not quite usable though)
