INPUT PINS Pin 7 on the Diagnostics port of the IPn3G can be used to detect an input. Pin 7 has a small wetting current (Vin) used to detect a contact closure, and prevent false readings by any noise or intermittent signals, it has a threshold sensitivity of 1.8V.
The IPn3G supports VPN IPsec Gateway to Gateway (site-to-site) tunneling, meaning you are using the IPn3G to create a tunnel between two VPN devices. The IPn3G can also operate as a L2TP Server, allowing users to VPN into the unit from a remote PC, and a L2TP Client.
Page 83
The Site to Site configuration allows the connection of two VPN devices to create a tunnel, such as a IPn3G router at the office and a VPN capable router at a teleworker’s home. To establish a tunnel, settings must be mirrored on the two routers. A successful connection requires that at least one router is identifiable by a static IP address or a Server ID.

4.0 WebUI Configuration 4.11.3 Tools > Diagnostic The Diagnostic menu provides Ping and Trace Route tools to use to test connectivity of the IPn3G. Image 4-83: Diagnostic Utilities A user can use the Ping command by entering the IP address of destination device in the Remote IP Address, use Count for the number of ping messages to send, and the Packet Size to modify the size of the packets sent.
This feature is particularly useful for rebooting remote units and has the same effect as power cycling the unit. Using the supplied interface, It is also possible to reboot the IPn3G on a schedule. Up to 10 tasks can be added to reboot the IPn3G at specific intervals if required. Both the Hour and Minute parameters are required to ensure the feature works as intended.
System > Summary screen in the WebUI.). 5.1.1 Serial Port To connect and access the AT Command interface on the IPn3G, a physical connection must be made on the RS232 DB9 serial port on the front of the IPn3G labeled ‘Diagnostic’. A terminal emulation program (Hyperterminal, Tera Term, ProComm, Putty etc) can then be used to communicate with the IPn3G.
5.1.2 Telnet (TCP/IP) Telnet can be used to access the AT Command interface of the IPn3G. The default port is TCP Port 23. A telnet session can be made to the unit using any Telnet application (Windows Telnet, Tera Term, ProComm etc).

Also, any traffic that is sent to the RJ45 port is sent directly out the WAN port and is not processed by the IPn3G. IP-Passthrough is ideal for applications where only a single device is connected to the IPn3G, and other features of the IPn3G are not required.

Step 1 Log into the IPn3G (Refer to Quick Start), and ensure that the Firewall is enabled. This can be found under Firewall > General. Also ensure that either WAN Request is set to Allow, which allows traffic to come in from the WAN, or that sufficient Rules or IP lists have been setup to allow specific traffic to pass through the IPn3G.

Test the connections. The IPn3G should only allow connections to the port specified from the Host A. An alternate means to limit connections to the IPn3G to a specific IP would have been to use the IP List Tool. By using Rules, we can not only limit specific IP’s, but we can also specify ports that can be used by an allowed IP address.
Question: How do I reset my modem to factory default settings? Answer: If you are logged into the IPn3G navigate to the Tools > Default Tab.
