Overriding a Profile’s NAT Configuration
“Overriding a Security Configuration”
Network Address Translation (NAT) is a technique to modify network address information within IP
packet headers in transit across a traffic routing device. This enables mapping one IP address to another
to protect network address credentials. With typical deployments, NAT is used as an IP masquerading
technique to hide private IP addresses behind a single, public facing, IP address.
NAT is a process of modifying network address information in IP packet headers while in transit across
a traffic routing device for the purpose of remapping one IP address to another. In most deployments,
NAT is used in conjunction with IP masquerading which hides RFC1918 private IP addresses behind a
single public IP address.
NAT provides outbound Internet access to wired and wireless hosts. Many-to-one NAT is the most
common NAT technique for outbound Internet access. Many-to-one NAT allows the access point to
translate one or more private IP addresses to a single, public facing, IP address assigned to a 10/100/
1000 Ethernet port or 3G card.
To define a NAT configuration or override that can be applied to a profile:
1 Select Devices from the Configuration tab.
2 Select a target device 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 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 screen’s Device Overrides field and select Clear Overrides.
This will remove all overrides from the device.
