  1. I am running a web server and have set up port forwardings (WAN...Virtual Server / Port Forwarding) for 80 and 443.
  2. I have DDNS set up. The registered DNS name resolves to my ISP-assigned IP address.
  3. I am able to reach the web server from outside internet and also from the LAN, in both cases by using its DNS name.
  4. I used YazFi to create a guest subnet. One way to guest=yes, client isolation=no. Machines on guest subnet can reach the internet.
  5. The web server is on the guest subnet.
  6. From a machine on the guest subnet, I can reach the web server at its subnet IP address.
  7. From a machine on the guest subnet, the server's DNS name resolves to my ISP-assigned IP address.
  8. From a machine on the guest subnet, I CANNOT reach the web server using its DNS name nor my ISP-assigned IP address: Connection timed out.
Can you suggest steps I can take to debug this?

Thanks,
-Steve

Are you able to reach the server via public IP from the main LAN subnet?

Yes, for point 3 it works both for the DNS name and also the IP (though in the latter case there are https cert warnings because there's no domain name).

Can you send me a copy of the diagnostics from YazFi please, option d at command line menu?
