I have a problem with my home-server. I installed some services (i.e. couchpotato) and I now want to access them from everywhere. A bit of context:
Here's the problem. When I use the ddns from the home server itself, I can access couchpotato, even using the IP address my.ip.ad.dress:5050 in the browser, instead of localhost:5050. But when I try do to the same from outside my lan, this fails. Whan I get though, connecting to the DDNS, is on port 80 the admin page of my personal rotuer.
I tried this tool https://www.grc.com/x/portprobe=5050 and it indeed signals the port as OPEN.
I guess this means that the DMZ of the landlord router is working, and port 80 is forwarded without any specifi additional rule, but port 5050 is not pforwarded, even if I added a rule for it.
