About 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.
