1.3 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.
If you are in need any of the following capabilities, then please make sure to contact your operator
or reseller the router-based modem:
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.
The 192.168.1.x subnet cannot be occupied by the Dovado in conjunction with these modems, as
the Hi-Link device occupies this subnet.
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.
The 192.168.1.x subnet cannot be occupied by the Dovado router in conjunction with these
modems, as the Hi-Link device occupies this subnet.
Some modem models might already occupy 192.168.0.1, therefore requiring your Dovado router to
use a different subnet’s IP address, such as 192.168.2.1.
There exists at least three known combinations of capabilities when it comes to ZTE router-based
modems
Version 1: (USB modems)
SMS is available
Port Forwarding is not available
IP address cannot be changed on the USB modem, but might be required on Dovado router
Version 2:(Mobile Hotspots devicesa and USB modem)
Port Forwarding is available
SMS is not available
Version 3: (Mobile Hotspots devices, not USB modem)
SMS is available
Port Forwarding is available
1.4 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.
Remote Management and Port forward notice
Not all Mobile Broadband operator, 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.
