When BIG-IP is configured with transparent vlan-group and traffic is matching a standard or fastl4 virtual-server and traffic hitting BIG-IP does not have a destination MAC address that belongs to BIG-IP - traffic will be L2 forwarded and pool member selection will not happen. This defect will also cause active FTP data connections over vlan-group to fail.
Server-side connections will fail.
All conditions must be met: - Traffic over transparent vlan-group. - Standard or fastl4 virtual-server. - Traffic has a destination MAC address that does not belong to BIG-IP. OR - Standard virtual server with FTP profile is configured. - Active FTP session is in use. - Traffic flows over vlan-group.
Use opaque vlan-group instead. OR disable db variable connection.vgl2transparent (15.0+)
