Access subdomain behind NAT with port specified

  • Let's say i have a reverse proxy behind NAT. My router blocks requests on ports 80 and 443 for security reasons (ISP provided modem/router).
  • Let's also say i have registered on duckdns.org, giving me a subdomain of sub1.duckdns.org.
  • Making a port forward, i am able to access sub1.duckdns.org:xxx, hitting the proxy.

How can i access my subdomains of that proxy?
GET'ing sub2.sub1.duckdns.org:xxx seems to translate org->duckdns->sub1->sub2
I need something like "sub2.(sub1.duckdns.org:xxx)"

Solution

  • I don't see how that's possible if duckdns doesn't provide such a service. Essentially, duckdns are returning an A DNS record for sub1.duckdns.org, which has nothing to do with the A record of sub2.sub1.duckdns.org.

    If you're using HTTP, perhaps something like sub1.duckdns.org/sub2 would be good enough?
