Some users of three mobile need to use DynDNS services so they can remotely access their router and any devices connected to their 3G Router. If you use the three.co.uk APN detailed above then you will not be able to use Dynamic DNS becuase the connection uses 3mobile NAT boxes.
In order to connect to the 3mobile network for ddns we recommend using the APN setting of 3internet which should bypass the NAT services and enable you to use DynDNS services for remote access.
There may be other APN settings available to enable this and the above APN setting might not work for all SIM cards and tariffs on the 3mobile network. If you are unable to get DynDNS working with this setting then please contact your service provider to discuss the best APN settings for your particular SIM card and Tariff.
If you want to receive a public IP address then you will need to use the APN of 3internet and set your router to 3G only - please note that 3mobile do not guarantee to provide your connection with a public IP address.
