Use Bridge NAT to manage Internet traffic originating at a remote site. In addition to traditional NAT
functionality, Bridge NAT provides a means of configuring NAT for bridged traffic through an access
point. NAT rules are applied to bridged traffic through the access point, and matching packets are
NATed to the WAN link instead of being bridged on their way to the router.
Using Bridge NAT, a tunneled VLAN (extended VLAN) is created between the NoC and a remote
location. When a remote client needs to access the Internet, Internet traffic is routed to the NoC,
and from there routed to the Internet. This increases the access time for the end user on the client.
To resolve latency issues, Bridge NAT identifies and segregates traffic heading towards the NoC and
outwards towards the Internet. Traffic towards the NoC is allowed over the secure tunnel. Traffic
towards the Internet is switched to a local WLAN link with access to the Internet.
To define a NAT configuration or override that can be applied to a profile:
1. Select Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service
platforms or Access Points.
2. Select a target device (by double-clicking it) from amongst those displayed within the Device
Configuration screen.
Devices can also be selected directly from the Device Browser in the lower, left-hand, side of
the UI.
3. Select Profile Overrides from the Device menu to expand it into sub menu options.
4. Select Security to expand its sub menu options.
5. Select Bridge NAT.
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 the Clear
Overrides button. This removes all overrides from the device.
