Final answer:
To correctly ensure customer traffic can pass through a JRSS Base firewall, one must verify and modify firewall rules and network address translation (NAT) settings.
Step-by-step explanation:
Verifying and Modifying Firewall Settings
To ensure customer traffic can pass through a JRSS Base firewall with limited permissions, two primary things need to be checked and possibly modified. These are the firewall rules and the network address translation (NAT) settings. It's essential to confirm that the firewall rules correctly allow or block traffic as intended, focusing on both inbound and outbound rules which match the customer's traffic patterns. Additionally, the NAT settings must be verified to ensure that the internal network addresses are being translated correctly to external addresses, facilitating the proper routing of traffic through the firewall. It's also crucial to apply these settings in a test environment before deploying in a live setting to minimize disruptions to customer traffic.
