Walter,

Thank you for your response.

So, would it be possible to move one of the logical VLAN's to the
physical level? The config would then look like this:

nameif ethernet0 NS-LAN-WAN security0
nameif ethernet1 MERCURIUS security5
nameif ethernet2 Stateful-failover security99
nameif ethernet3 VBS-PRD security95
nameif ethernet4 VBS-ACC security75
nameif ethernet5 DMZ-PRD security55

interface ethernet3 vlan95 physical
interface ethernet3 vlan90 logical
interface ethernet4 vlan75 physical
interface ethernet4 vlan70 logical
interface ethernet5 vlan55 physical
interface ethernet5 vlan50 logical

nameif vlan90 VAS-PRD security90
nameif vlan70 VAS-ACC security70
nameif vlan50 DMZ-ACC security50

ip address NS-LAN-WAN 172.16.0.6 255.255.0.0
ip address MERCURIUS 10.255.3.2 255.255.255.0
ip address Stateful-failover 10.255.0.1 255.255.255.252
ip address VBS-PRD 10.255.2.65 255.255.255.192
ip address VBS-ACC 10.255.2.1 255.255.255.192
ip address DMZ-PRD 10.255.8.1 255.255.254.0
ip address VAS-PRD 10.255.6.1 255.255.254.0
ip address VAS-ACC 10.255.16.1 255.255.254.0
ip address DMZ-ACC 10.255.18.1 255.255.254.0


And the of course a trunk to the switch.

TIA

Patrick
