Configure IP passthrough
IP passthrough is a useful feature if a host computer or server on the local area network needs to
have access to it from the Internet with a public IP address. With IP passthrough configured, all IP
traffic, not just TCP/UDP is forwarded back to the host computer. This feature can be useful for
applications that do not function reliably through network address translation.
In this configuration, the local PC shares the public IP addressing information with the WAN side of the
router.
