WAN Backhaul Override Configuration
A Wireless Wide Area Network (WWAN) card is a specialized
network interface card that allows a device to connect, transmit and receive data
over a Cellular Wide Area Network.
The RFS 4000
controller has a PCI Express card slot that supports 3G WWAN cards.
The WWAN card uses point to point protocol (PPP) to
connect to the Internet Service Provider (ISP) and gain access to the
internet. PPP is the protocol used for establishing internet links over dial-up
modems, DSL connections, and many other types of point-to-point communications. PPP
packages your system's TCP/IP packets and forwards them to the serial device where
they can be put on the network. PPP is a full-duplex protocol that can be used on
various physical media, including twisted-pair or fiber optic lines or satellite
transmission. It uses a variation of High Speed Data Link Control
(HDLC) for packet encapsulation.
To define a WAN Backhaul configuration override:
-
Select WAN Backhaul.
Note
A blue override icon (to the left of a parameter)
defines the parameter as having an override applied. To remove an override
go to the
Basic
Configuration section of the device and click
Clear Overrides. This
removes all overrides from the device.
-
Refer to the WAN (3G)
Backhaul configuration to specify WAN card settings:
WAN Interface Name |
The WAN Interface name for the WAN
3G Backhaul card. |
Reset WAN Card |
If the WAN Card becomes
unresponsive or experiences other errors, click
Reset WAN Card to power cycle and
reboot the WAN card. |
Enable WAN (3G) |
Select to enable 3G WAN card
support on the device. A supported 3G card must be connected
to the device for this feature to work properly. |
-
Define or override the following authentication parameters in the
Basic Settings field:
Username |
Provide a username for
authentication support by the cellular data carrier. |
Password |
Provide a password for
authentication support by the cellular data carrier. |
Access Point Name (APN) |
Enter the name of the cellular
data provider if necessary. This setting is needed in areas
with multiple cellular data providers using the same
protocols, such as Europe and Asia. |
Authentication Type |
Specify the authentication type
used by the cellular data provider. Supported authentication
types are None, PAP, CHAP, MSCHAP, and MSCHAP-v2. |
-
Define or override the following NAT parameter in the Network
Address Translation (NAT) field:
NAT Direction |
Define the Network Address
Translation (NAT) direction. Options include:
Inside |
The inside network is transmitting data over the
network its intended destination. On the way out,
the source IP address is changed in the header and
replaced by the (public) IP address. |
Outside |
Packets passing through the NAT on the way back
to the controller or service platform managed LAN
are searched against to the records kept by the
NAT engine. There, the destination IP address is
changed back to the specific internal private
class IP address in order to reach the LAN over
the network. |
None |
No NAT activity takes place. This is the default
setting. |
|
-
Define or override the following security parameters in the Security
Settings field:
IP Inbound Firewall Rules |
Select an inbound IPv4 ACL to
associate with traffic on the WAN backhaul. This setting
pertains to IPv4 inbound traffic only and not IPv6. IPv4
operates as a best effort delivery method, as it does not
guarantee delivery, and does not ensure proper sequencing or
duplicate delivery (unlike (TCP). IPv4 hosts can use link
local addressing to provide local connectivity. If an
appropriate IP ACL does not exist, click
Add to create a new one. |
VPN Crypto Map |
If necessary, specify a crypto map
for the wireless WAN. A crypto map can be up to 256
characters long. If a suitable crypto map is not available,
click Create button to configure a
new one. |
-
Define or override the following route parameter in the Default
Route Priority field:
WWAN Default Route Priority |
Use the spinner control to define
a priority from 1 - 8,000 for the default route learned by
the wireless WAN. The default value is 3000. |
-
Click OK to save the changes and
overrides made to the WAN Backhaul screen.
Click Reset to revert to the last
saved configuration.
