Configuring the Advanced Settings
If you have activated the device's DynDNS function, it will monitor its public IP address.
When this changes, it will open a connection to DynDNS.org and update its IP address
there.
Please remember:
You have to open an account with DynDNS.org before you can use the Gigaset SE551

sary information when registering with your Service provider.
