Edit: Big thanks to everybody who shared their advice! :)
I'm very pleasantly surprised and will definitely explore all the options you guys provided, such as getting an additional router or configuring Tailscale. Again, big thanks to everyone!
Hi all, I've recently moved and now my ISP doesn't allow port forwarding for wired connections (wifi only), and my landlord does not allow changing ISPs. Now my home server is practically useless which makes me very sad.
Is there any easy way to still access device ports without port forwarding or buying a wifi card/dongle is my safest bet?
Not what you're asking but since it's been covered well:
Buy your own cable modem and put your own firewall behind it. Not only will this save you money in the long run, you'll also have no issues with things like port forwarding. I use Comcast/Xfinity with a docsis3.1 cable modem + a decent firewall and it's a good way to go.
you cannot use a docsis cable modem behind an already 'running' connection, you need a cable to connect it to
also you need an isp that allows your modem to connect to (in docsis authentication is usually done via the mac address of the modem)
(cable is not an ethernet cable in this whole context but a specific type of 'tv' cable)
i'm not sure how you think 'buying a cable modem' would solve ops problems.
