Limited Internet Mode (L.I.M.)
Dovado routers support most Hi-Link (Huawei) and CWID (ZTE)-based USB modems. However,
unlike traditional USB modems, these specific models are designed to act as routers, imposing
certain limitations due to the complication of a second private network layer.
Limitations with Huawei Hi-Link modems:
UPnP, SMS and Bridge Mode cannot be used.
Port Forwarding is limited to a maximum total of 15 individual rule assignments.
Limitations with ZTE CWID modems:
UPnP and Bridge Mode cannot be used.
Port Forwarding does not work (at all) on certain models.
SMS is limited to certain models.

Direct interface vs PPTP interface
The Dovado router can have two IP Interfaces connected to the Internet: Direct Interface and
PPTP Interface. It is possible to access the router and clients behind it via both interfaces using
their IP addresses
Direct Interface this is the router's own interface which it normally uses to communicate on
the Internet
PPTP Interface this interface exists when a VPN PPTP service is used. When PPTP is used
the router has two IP addresses to the Internet.
1.5
Remote Management and Portforward
Not all Mobile Broadband operators, ISP and VPN providers allow external access to your router
from the Internet. If the provider blocks such access it is not possible to use Remote Management
or performing port forwards. Please contact your Internet Service Provider if you are having
problems with accessing the router from the Internet.

Status Overview Bar
Atop of the user interface, a bar displays an overview of your Internet connection.
This information sits outside the security zone of your router, and does not need to be accessed via
an authorized login, thus saving time on checking the connection status.
The Connection Status Overview Bar shows the following information:
Date: Synchronized with a Dovado NTP (Network Time Protocol) server upon each new successful
Internet connection.
Signal: The latest measurement gathered by the USB modem upon connection is displayed in a
percentage value, along with the technology (2G, 3G or 4G).
