USG110 - LTE failover - VPN / Access

creeko

Hi everybody,

we are using a USG 110 in our company and besides a DSL line we set up a mobile connection (LTE) via USB as failover.
Is there a way to setup also a VPN tunnel with this mobile connection without static public ip or to get access to the device from outside the company in another way in case DSL is down? 
Thank you very much in advance for your help.
Best regards

Hi Zyxel_Charlie,
Thanks for your answer. This is helpful to add a dyndns record.
The problem is however, that the cellular interface shows only the internal IP (in this case 192.168.1.100) and not the public IP and so only this internal IP is forwarded to no-ip.
Is there a possibility to forward the public IP to no-ip instead?

The USB dongle is a Huawei E3276s-150 as mentioned as  compatible 3G dongle in the official ZyXEL list.
Thanks a lot.
