What is DDNS? Dynamic IP changes frequently, so it is impossible to deliver it externally or connect to the domain such as . In such an environment it is very inconvenient to access from outside, so DDNS enables you to access via the same domain whenever the IP changes by reflecting this to DNS.

What is UPnP? This is the function which helps to control Port easily. By just activation the UPnP function, it makes access to LG NAS inside router possible from outside router.
