Question
A firewall administrator wants to be able to see all NAT sessions that are going through a firewall with source NAT.
Which CLI command can the administrator use?
A. show session all filter nat source
B. show running nat-rule-ippool rule “rule_name”
C. show running nat-policy
D. show session all filter nat-rule-source
Answer
A. show session all filter nat source
Explanation
The correct CLI command to view all NAT sessions that are going through a firewall with source NAT is “show session all filter nat source”.
This command displays active sessions on the firewall, filtered to show only those sessions that have undergone source NAT. Source NAT changes the source IP address of a packet as it traverses the firewall, typically to allow internal hosts to access the internet using a public IP address.
By filtering the session table with “filter nat source”, the administrator can see the original source IP address, the translated source IP address, and other details about the active NAT sessions. This information is useful for troubleshooting NAT-related issues, monitoring traffic patterns, and analyzing the utilization of NAT resources.
