Good morning,

It's been a long time since I had a domain and I can't seem to work out how to sort this out. I'm fairly confidant with local networking but this just has my brain muddled.

I bought a domain, X. My internet connection is a dynamic IP, so I set up a NO-IP dns address, Y. The local address of my server is Z.

I've set up a port forward rule in my router for port 18465 to Z.

I've pointed my dyn dns Y at Z.

I've pointed X at the DNS servers given by NO-IP and set CNAME "www" to Y.

I cannot connect to my public IP address, Y or X from outside the network.

Any pointers on what I've missed or what I can try are much appreciated.

Cheers.

With you saying you cannot connect to your public IP from outside the network, my first guess would be, is the port forwarding working correctly?

You can verify the port forwarding is working by using something like http://canyouseeme.org/ to confirm it can be seen outside your network.

If not, then it is possible that this is not working correctly, or that the IP address you have is a CG-NAT IP address rather than a public IP address.

I'd recommend checking those two things first and once the port forwarding is working, then technically the rest of it should work.

I have exactly the same setup. Domain name with a cname record to home @ my domain.

I only have port 563 open (which is smtps I think - but I'm using it for SSH). But you should be able to access your domain with it's ip address, and with your no ip address and then lastly with your domain address.

Windows firewall?? (Assuming your "server" is windows based)

Hi folks,

Server is a linux box.

I can now access my Plex server at [public ip address]:32400/web and [dynamic dns]:32400/web.

How can I make my [domain] point to [dynamic dns]:32400/web?

Currently I have a CNAME record which points to "[dns]." (note the period).

Any help is appreciated :)

Cheers

So lets say you want plex.example.com to point to your dynamic dns host name. And lets say that is plex.dyndns.tld

The DNS setup for that would be

plex.example.com IN CNAME plex.dyndns.tld

You don't add any port numbers.

Various systems will do the setup for that differently, so refer to the manual.

PS: Usually, if you have a dot after an entry, thats to signify it being a full domain, not a host of the domain. Some more info on that here.

PPS: DNS won't let you "make my [domain] point to [dynamic dns]:32400/web?". You can have your domain serve up the dynamic dns ip-address. But you would have to deal with the http redirect on your server on the dynamic ip-address to have it send you to the right port and URI. That should typically be a straight forward redirect on the web server at the dynamic dns ip-address.

A bit off topic but duckdns.org is great to use as it's free without having to manually renew every month.

Cheers, Matt.

Can you point me in the right direction? I'm running apache2 and ubuntu server. After some googling I can't seem to figure it out.

Cheers
