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:
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.
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.
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.
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?
