Multicast traffic does not work with SecureXL on Vlan interfaces Technical Level
  • Multicast traffic arriving to Security Gateway / Cluster, but does not leave through the outbound interfaces when a mix of multiple Vlan and non Vlan outgoing interfaces are configured.
  • Turning off SecureXL resolve the issue.

When traffic is sent to multiple interfaces, SecureXL makes a copy of the packets. However, the VLAN tag information is also being propagated.
