Unable to connect to the guest network because port 10080 is blocked, why no way to accept the risk and continue?

If you want to run your own Certificate Authority, or want to trust private self-signed certs, that all works fine. Have at. Or get free certs from LetsEncrypt or other providers, if you want to avoid loading your trust root via Apple Configurator 2 app or other such. That’s also all entirely unrelated to TCP 10080 and NAT Slipstreaming.

What is slipstreaming? “NAT Slipstreaming allows an attacker to remotely access any TCP/UDP service bound to any system behind a victim's NAT, bypassing the victim's NAT/firewall (remote arbitrary firewall pinhole control), just by the victim visiting a website.” It’s an enormous hole.

The usual recommendation for those ill-advisedly using 10080 is to move the web server to a different and safer port. TCP 443 and 8443 are common choices for web servers offering HTTPS services, of course. 8080 is a fairly common choice for HTTP connections.

Right now, changing the web server server port change, or maybe establishing port forwarding through the target web server or through some other local network server to allow indirect access to TCP port 10080 on the target web server is about the only way you’ll get to TCP 10080 from pretty much any current web browser. And I’d stay off 10080.

To put it bluntly, 10080 is a dead port.

If LinkSys was implementing TCP 10080, check with them for suggestions or for firmware updates.

While it may seem convenient to have the ability to accept the risk and continue, it also poses a significant security concern. Allowing users to bypass such restrictions could potentially expose them to malicious attacks and compromise the overall network security.

Regarding your point about Wi-Fi networks being less secure, there are alternative solutions available. Many routers nowadays offer separate guest networks that allow limited access while keeping the main network secure. This way, you can still provide a separate network for guests without compromising the overall security of your Wi-Fi.

In situations like this, it is always best to explain what you are seeing. Ideally, provide a screenshot.

Because I have no idea what you are talking about.
