I’m in a similar situation. Before I had to move all was fine, I had a single ethernet port I plugged my router into. It even had a static IPv4 (even though no IPv6 but I could just use tunnelbroker). Literally perfect.

After I moved I’m now stuck in this horribly designed network that has a stupid internet cafe tier login portal even for wired devices, unencrypted wifi, seemingly every single device from every student on the same network (I am getting blasted with other people’s broadcast packets and I’m pretty sure the network congestion from that is where my weird intermittent packet loss comes from). And now I don’t have any public IP address at all.

Whoever they hired to set this up is an absolute moron who has no idea about network security or how to make an efficient network and considering the internet cafe login portal probably likes to cause as much suffering as possible. (Not saying I’m necessarily qualified but the fact alone that I can connect to other people’s AirPlay devices means they failed at both.)

And the reason all of this is a problem is that they also don’t allow putting a router/firewall in front so I can get a sane network. Had to tear down pretty much all the infrastructure I set up in the old place because a lot of it was relying on me having control over the network. Of course, I knew none of this before I moved in, I was explicitly looking for internet shenanigans in the contract.

I now have a janky Wireguard mesh network setup with one of the machines being the IPv6 gateway. Awful but at least I have public addresses and IPv6 (and with that a bit of my own network space) again.
