Web server accessible with no port forwarding!
First let me just say I have no idea if I'm in the right subject area of these forums. Mods, please move appropriately if I'm in the wrong place. Thank you. I'm using a Netgear C7000v2. I had previously opened ports 80 and 443 while testing a new server set up on an old Mac. I ISP is Comcast. I just discovered my server is accessible over the Internet. I tested using my cell phone's browser. This is alarming because I have NEITHER port 80 OR 443 forwarded through the router. They were opened shortly during server testing but I deleted the settings and restarted the router. Afterward I can still access the server. I have used port forwarding many times over the past two decades and never seen this before. Can anyone help me understand why this is occurring?
Guess again. DHCP, while it does work, makes any device that requires it unable to connect to the internet at all. The period I put up there should have been followed by a big fat âť“
Proper solution is turn of UPnP entirely (leave dhcp on, simply setting the server box to static IP in its own settings). Phones are all happy and the server can no longer be reached from outside. Anyone got any extra hair to replace what I lost over the past day? 🙄

Ports 80 and 443 are generally open as they are the main ports used for general internet access.
Are you certain you are fully understanding the issue? I'm not speaking of access to the internet from my network. I'm speaking of internet access to my network via 80 and 443. Neither of those are "normally open" to serve web pages from WITHIN my LAN/WAN. Twenty years of running local servers and I've NEVER seen this without port forwarding set up.
Have you tried a factory reset and setup from scratch to see if this stops this?
