Some Internet services require special handling in a multi-WAN environment. The BD1000 supports han-
dling these services so that that Internet applications do not notice it is behind a multi-WAN router.

Description
SIP
With Voice-over-IP (VoIP) Session Initiation Protocol (
SIP
), the BD1000 acts as a SIP
Application Layer Gateway (ALG) that binds connections for the same SIP session to the
same WAN connection, and translates the IP address in the SIP packets correctly in NAT
mode.
This type of passthrough support is always enabled. Available options include
Standard
Mode
and
Compatibility Mode
.
If your SIP server’s signal port number is non-standard, check the box
Define custom
signal ports
and enter the port numbers into the text boxes.
H.323
With
H.323
enabled, the BD1000 defines protocols that provide audio-visual communi-
cation sessions on any packet network to passthrough the BD1000.
FTP
FTP
sessions consist of two TCP connections
—
one for control and one for data. In multi-
WAN situations, FTP sessions must be binded to the same WAN connection. Otherwise,
problems will arise when transferring files.
By default, the BD1000 monitors TCP control connections on port 21 for any FTP connec-
tions 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, check the box
Define
custom control ports
and enter the port numbers into the text boxes.
TFTP
The BD1000 monitors outgoing
TFTP
connections and routes any incoming TFTP data
packets back to the client. Select
Enable
if you want to turn on
TFTP Passthrough
support.
IPSec NAT-T
With
IPsec NAT-T Passthrough
enabled, the BD1000 monitors UDP ports 500, 4500
and 10000 by default.
Select the box
Define custom ports
to add more custom data ports for your IPsec sys-
tem. If the VPN contains IPsec Site-to-Site VPN traffic, you must check the box
Route
IPsec Site-to-Site VPN
and select the
WAN connection
to route traffic.
If you have
IPsec Site-to-Site VPN
traffic routed, check the
Route IPsec Site-to-Site
VPN
option and select a
WAN
to force routing traffic to the specified WAN.
