My dyndns domain doesn't point to the right IP from inside my network, how do I correct that?

I set up a DynDns account to point a domain to my dynamic IP server at home. From any "outside" network, the connection is working and pointing to my server. But when I point my browser to my URL (xxxx.dyndns.org) from within my LAN it goes to the login page of my ADSL modem.

What am I doing wrong?

Solution 1:

You're not doing anything wrong, this is exactly how DynDNS works. DynDNS is returning your public IP for your home internet connection, which the router responds on. Because you are inside the network, it is assuming you want to connect to the router itself and not the port forwarding rules because you are already behind the firewall. To be able to use your DynDNS URL inside your network, your router needs to support NAT reflection (or port reflection). This allows internal users to connect to your public IP and it reflects back to the right internal IP through the router's port forwarding rules.

If you don't have this, you will need to either run dual DNS, or use other methods such as overriding your hosts file when internal on the network.
