Severity: 3-Major


When BIG-IP is configured with transparent vlan-group, virtual server which does port-translation and traffic hitting BIG-IP does not have a destination MAC address that belongs to BIG-IP - there will be no destination port translation performed on the server-side.


Server-side connections will fail.


All conditions must be met: - Transparent vlan-group. - Virtual server with port translation. - Traffic has a destination MAC address that does not belong to BIG-IP.


Use opaque vlan-group instead.
