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
