Cellular Failover for Dual WAN Routers Using IP Passthrough

When primary access to your Dual WAN Router is interrupted, Cellular Failover can provide a convenient alternate avenue for communication with remote network installations and branch offices. During WAN outages, a WTI Device equipped with the W4G LTE Cellular Modem Option can employ the IP Passthrough function to allow communication that would normally be carried by the primary WAN to be conducted via the 4G LTE Cellular Modem. This essentially enables you to use your cellular provider in place of backup ISP.

Cellular Failover for Dual WAN Routers (IP Passthrough)

If your Dual WAN Router senses that communication via the primary WAN is down and diverts traffic to the secondary WAN port, a WTI Device connected to the secondary port can then transmit communication traffic to the Internet via the optional 4G LTE Cellular Modem. This helps to ensure reliable communication during outages, cutting downtime and loss of service without the need for a secondary ISP.

This also allows the WTI Device to serve a dual purpose. In addition to performing its normal role, providing remote access to console port command functions and power switching and reboot capabilities, a WTI Device that includes the W4G Cellular Modem Option can also serve as a means for secondary WAN communication via cellular in the event that the primary WAN connection fails or is interrupted.

WTI DSM Series Console Servers and CPM Series Console Server + Power Control Combo units are both available with the W4G LTE Cellular Modem Option with Cellular Failover capabilities. The W4G Cellular Modem Option is available for AT&T, Verizon and World cellular carriers.
