DDNS: Cannot access DDNS from home network

If you cannot access your Dynamic Domain Name System (DDNS) at home, the issue may be caused by a networking issue known as NAT Loopback / Hairpinning. This means that while you are inside the network, you cannot use an external IP address / DDNS.

To resolve a NAT Loopback / Hairpinning issue:

  1. Launch your Client software or app on your smartphone, tablet, or PC / Mac.
  2. In Device Manager, add the same product a second time to create two connections.
  • Create one connection for when you are home and using the internal IP address.
  • Create one connection for when you are away and using an external IP address / DDNS.
