Requirements
• Public IP address in the mobile network (or also for wired Internet connections).
(Note: Many mobile operators oer taris for business customers to access mobile devices, e.g. T‑Mobile IP VPN
or Vodafone CDA. Furthermore, there are providers who provide you with a public IP address via a conventional
mobile phone card).
• Router Firmware 1.0.0.r9919 or higher
Port Mapping Notes
The following information must be available for port mapping to be set up:
• IP address of the device that is to be accessed
• Port to be redirected (e.g. http/80 from the device that is to be accessed).
Example Welotec Router
LAN IP address:
192.168.2.1
Subnet mask: Webcam 255.255.255.0
LAN IP address: 192.168.2.2
Subnet mask: 255.255.255.0
Standard Gateway: 192.168.2.1
The webcam has an interface that can be accessed via http://192.168.2.2.
(Note: http protocol uses TCP port 80)
For a working port mapping it is helpful to check the settings of the connected devices in advance. The following
checklist is helpful (according to the example above):
• Does the camera have the IP address 192.168.2.2?
• Does it respond to “ping 192.168.2.2”?
• Is the web interface of the camera accessible via http://192.168.2.2?
• Is the Welotec router entered as the default gateway for the camera (192.168.2.1)?
If these conditions are met, the port mapping can be set up according to the following instructions.
