This sort of thinking is endemic in industrial networks; they finally internalized basic ipv4 concepts in the late 00s and never considered maybe the stateful tracking required for UPNP and other NAT tricks also might exist without it. I've set up several private v6 networks to deal with renewable energy projects in which the integrator used the same ipv4 address blocks on every single one, and the whole 6to4 translation explanation landed like they had just seen a devil sorcerer graft a goat head onto a human.

There are many, many networking and originally UNIX tools tricks (e.g. SSH) you can show to the poor people supporting industrial networks/ hardware. I have written some of my tricks down in this OrgPage: https://www.orgpad.com/s/UHUor4 https://www.orgpad.com/s/UHUor4 there are screenshots for Linux and Windows for some things related to SSHFS, SOCKS Proxy and more. Click units with shadows to open them. From time to time, I update it to reflect new tricks. This knowledge saved at least 2 companies hundreds if not thousands of euros in on-site support, hardware and other expenses. Funnily, while these things are quite hacky, they tend to work better than most of the dedicated hardware I have seen in practice, while keeping you/ the technician/ engineer in control. With any kind of working infrastructure, you can estimate how good your solutions are because you don't get called at random times and from monitoring/ explicit contact you just see/ hear the things work fine.

    I tried just now in two different Firefox (ESR and current) versions and it works. Perhaps you have to enable JavaScript, since OrgPad is a web application? You can also try this not-shortened link: https://www.orgpad.com/o/AWhUSD7lhAjYC0sw-9lcDd https://www.orgpad.com/o/AWhUSD7lhAjYC0sw-9lcDd

      Disabled uBO, still no luck. It says "Computing sizes of all cells, 50 remaining ..." and spins forever.
