- **Description**: Firewalls that use the ipsec-sa action to forward traffic to an IP Security (IPSec) security association (SA) cannot be configured on the ES PIC that services the SA. That configuration creates traffic loops within the router and was probably unintended. The problematic firewall was automatically removed from the indicated interface.
