ISP, DNS or what?
I don't know how or what to setup anymore, or how to approach this issue.
I have setup my Firewalla purple SE in in router mode, it is handling all DNS, DHCP and firewall rules. I can't seem to reliably access my internally hosted services. Sometimes it works, mostly it doesn't. This setup was working with a previous router that I was using.
- nsloookup to the website address shows my public IP. I am not behind double NAT as the IP on the WAN interface is the same as the IP shown when I visit whatsmyip.com
- I have setup 2 port forwarding rules, under network, nat settings, port forwarding. They allow the ports in, and put them on the corrected ports for my SWAG proxy server to respond to them.
- when I hit external port scan, it shows me that no ports are open. Shouldn't they be opened by the NAT rules?
What can I try next?

I think this is solved. When I setup the NAT rule, I set it for the device name, which I believe is derived from the MAC address. When the device was upgraded and rebooted, it changed it's MAC address, and thus turning off the NAT rule, which is why it wasn't showing up in external port scans. I have changed the NAT rule to be pointing to the IP address now, which seems to have solved my problems.

I am not so sure how to do it, or even if I need to do it. It is my server that is running Unraid, which I just updated to 6.12.3 version last night, which is what changed the MAC address. I think this might have something to do with the latest problems that they were having with macvlan/ipvlan. Before now, this wasn't an issue. I have searched MAC randomization on Unraid and got nothing back. I already have the server on a static IP, so I am fine using the firewall rule linked to that static IP.
