5.4.5.5.8 Overriding the Profile’s Bridge NAT Configuration
Profile Security Configuration
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 Bridge NAT configuration that can be applied to a profile:
1. Select the Configuration tab from the Web UI.
2. Select Devices .
3. Select Device Overrides from the options on left-hand side of the UI.
4. Expand the Security menu and select Bridge NAT .
Interface Select the VLAN (from 1 - 4094) or WWAN used as the communication medium between
the source and destination points within the NAT configuration. Ensure the VLAN selected
adequately supports the intended network traffic within the NAT supported configuration.
Overload Type Define the overload type utilized when Several internal addresses are NATed to only one
or a few external addresses. Options include
NAT Pool, One Global Address and Interface
IP Address . Interface IP Address is the default setting.
NAT Pool Provide the name of an existing NAT pool for use with the dynamic NAT configuration.
Overload IP If One Global IP Address is selected as the Overload Type , define an IP address used a
filter address for the IP ACL rule.
NOTE: Bridge NAT supports single AP deployments only. This feature cannot be used in
a branch deployment with multiple access points.
