Passthrough .
Some Internet services need to be specially handled in a multi-WAN environment. Pepwave
routers can handle these services such that Internet applications do not notice being behind a
multi-WAN router. Settings for service passthrough support are available here.

Service Passthrough Support
Session initiation protocol, aka SIP, is a voice-over-IP protocol. The Pepwave
router can act as a SIP application layer gateway (ALG) which binds
connections for the same SIP session to the same WAN connection and
translate IP address in the SIP packets correctly in NAT mode. Such
passthrough support is always enabled, and there are two modes for selection:
Standard Mode and Compatibility Mode . If your SIP server's signal port
number is non-standard, you can check the box Define custom signal ports
and input the port numbers to the text boxes.
With this option enabled, protocols that provide audio-visual communication
sessions will be defined on any packet network and pass through the Pepwave
router.
FTP sessions consist of two TCP connections; one for control and one for data.
In a multi-WAN situation, they must be routed to the same WAN connection.
Otherwise, problems will arise in transferring files. By default, the Pepwave
router monitors TCP control connections on port 21 for any FTP connections
and binds TCP connections of the same FTP session to the same WAN. If you
have an FTP server listening on a port number other than 21, you can check
Define custom control ports and enter the port numbers in the text boxes.
The Pepwave router monitors outgoing TFTP connections and routes any
incoming TFTP data packets back to the client. Select Enable if you want to
enable TFTP passthrough support.
