When a working host's MAC address is changed, the Security Gateway does not update its Linux ARP with the new MAC address Technical Level
Symptoms
  • When a working host's MAC address is changed, the Security Gateway does not update its Linux ARP with the new MAC address. The issue occurs if traffic initiated by the host uses the TCP protocol.

Cause
When SecureXL forwards the traffic to the Security Gateway for PXL processing, the Security Gateway does not at intervals send an ARP request to learn the new host's MAC address.
