Limited access to Umbrel

I can access Umbrel from my desktop computer, from another subnet, but I can’t access from a computer from the same subnet…

  1. Nmap from Desktop shows port 80 open, and I can login like normal

Host is up (0.00039s latency).
PORT STATE SERVICE VERSION
80/tcp open http nginx 1.17.8
|_http-server-header: nginx/1.17.8
|_http-title: Umbrel

  1. Nmap from Computer shows port 80 as filtered, and any attempt to get a status from Umbrel times out.

Host is up (0.00031s latency).
PORT STATE SERVICE VERSION
80/tcp filtered http

All I really want to do is to have my dashboard running on “Computer” to be able to show that Umbrel is up. I couldn’t find the firewall settings that are blocking my requests for status. Not in the iptables in the OS, so I think it’s somewhere in the web of docker containers within Umbrel… maybe something like a reverse proxy?

Checking the network interfaces, I see there’s a ton of IPV6 on my Umbrel instance, could that have something to do with this?
