    uPNP part is missing in the summary as one of the options for how to make port forwarding.
    for the next video, I would show ipv6 with examples - we don't need nat but at the same time how don't open any home device into the internet, etc.

    A video going into detail for LTE, cell locking, and carrier aggregation.
    In a water bottling facility in Mount Athos, I am facing issues with my mobile operator.
    The cell tower that is located above Daphne is around 300m from the 4g router, and has power saving features enabled on high frequency bands, causing the router to drop connection to the cell tower.
    The router then establishes connection at cell towers located in Ierisos that is located around 36 ΚΜ, or at Sarti that is around 25km away, and located on the left of the dish. I am using a RBLHGR&R11e-LTE and waiting for a LHG LTE18 kit to arrive soon.

      Currently version 7 is behaving like other manufacturers. You must have your prefix in the FIB so that it can be announced. In fact, not only that, but you need to create an addres-list with it and also send it in the out (export) filter.

    Video idea - CAKE and queue trees. There is also lack of documentation from your side on Cake, so I guess video would do it. Personally I expect you to show off how to setup up CAKE with proper parameters and set up queue tree, all for home/homelab users. I would like to see general recommendations on what kind of queues you might recommend, how to prioritize primary network and give "leftover" traffic to guest network or seedbox. Also - great video!

    Thank you for the video! Tell us how SNAT works for protocols other than TCP and UDP, for example ICMP, GRE, IPIP, etc. How does a router keep track of connections when several hosts on the local network behind a NAT send ICMP requests to the same host on the Internet? How does he understand which host on the local network to return the ICMP reply to?
