802.1q tagged sub-interfaces on PA-500 v6.1 not working

L0 Member

I'm trying to consolidate multiple Layer3 interfaces into a single Layer3 interface using subinterfaces and VLAN tagging, but it's not working.

I'm hoping someone can point out the error in my configuration.

The current working configuration:

FIREWALL
ethernet1/2 - 192.168.102.254, untagged, zone 102

ethernet1/3 - 192.168.103.254, untagged, zone 103

ethernet1/4 - 192.168.104.254, untagged, zone 104

ethernet1/5 - 192.168.105.254, untagged, zone 105

VirtualRouter1 - ethernet1/2, ethernet1/3, ethernet1/4, ethernet1/5

SecurityPolicy - rules in place that allow communication between zones.

SWITCH

port2 - access port, vlan 102 <-> ethernet1/2

port3 - access port, vlan 103 <-> ethernet1/3

port4 - access port, vlan 104 <-> ethernet1/4

port5 - access port, vlan 105 <-> ethernet1/5

I attempted the configuration below but after the commit nothing could be accessed through the firewall.

FIREWALL
ethernet1/2 - no IP address, no zone

ethernet1/3 - no IP address, Layer3

   ethernet1/3.102 - 192.168.102.254/24, tagged 102, zone 102.

   ethernet1/3.103 - 192.168.103.254/24, tagged 103, zone 103.

   ethernet1/3.104 - 192.168.104.254/24, tagged 104, zone 104.

   ethernet1/3.105 - 192.168.105.254/24, tagged 105, zone 105.

ethernet1/4 - no IP address, no zone

ethernet1/5 - no IP address, no zone

VirtualRouter1 - ethernet1/2, ethernet1/3, ethernet1/4, ethernet1/5, ethernet1/3.102, ethernet1/3.103, ethernet1/3.104, ethernet1/3.105

SecurityPolicy - same zone rules in place from working configuration.

SWITCH

port2 - shutdown

port3 - tagged vlans 102, 103, 104, 105

port4 - shutdown

port5 - shutdown

Conceptually, this all looks correct.  I've had similar configurations working.

What symptoms or errors do you have?

Is the interface link up?

Any errors on the switch or firewall?

Any logs?
