SIP
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 c
orrectly 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 inp
ut the port numbers
to the text boxes.
H.323
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
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 connect
ions 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.
TFTP
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.
IPsec NAT-T
This field is for enabling the support of IPsec NAT-T passthrough
. UDP ports 500,
4500, and 10000 are monitored by default. You may add more custom data ports
that your IPsec system uses by checking Define custom ports.
If the VPN
contains IPsec site-to-site VPN traffic, check Route IPsec Site-to-
Site
VPN and choose the WAN connection to route the traffic to.
