IP Passthrough Failover

Product Discussion Other Products
#1

hi sir, from your website mention the IP passthrough failover:
While using IP Passthrough, routers can now failover from a Ethernet WAN to a Cellular WAN, using public IP addresses throughout the whole process.

Does it mean let say I got 1 x internet link with fixed public IP (Ethernet WAN) and 1 x mobile broadband (cellular WAN -does not have any public IP, or some time when it connect to internet is running in private IP) ,

when the internet link with fixed IP is down, we still can access the peplink thru mobile broadband with the fixed public IP on ethernet WAN ?correct me if I am wrong. thanks.

There are 2 public IP address as shown in the screenshot above.

DSL Public IP and LTE Public IP

In IP Pass-through mode, device behind Peplink will direct retrieve Public IP address from the service provider and in the event fail-over happen from DSL to LTE, device will obtain IP address from LTE network. This will allow fail-over from 2 different ISP and the device is using public IP addresses throughout the whole process.

Hope this explained your concern.

For some enterprise network requirements, they need the device owing the LTE public address instead of using inbound NAT. IP Passthrough allow device direct obtain the IP from the service provider network that will full fill the requirement.
