Configuring a NAT Security Policy
To configure NAT, you must first:
• configure a NAT security profile and policy in the config>security context
→ in the config>security>profile context, specify the timeouts for the
tcp/udp/icmp protocols. This step is optional. If you do not configure the profile,
a default profile is assigned.
→ in the config>security>policy context, configure a NAT security
policy, and specify the match criteria and the action to be applied to a packet if a
match is found
• then configure a NAT zone and apply the policy ID to the zone
To configure a NAT policy, you must create the policy ID.
