The pix can support both vlan 1 and vlan 100 on the same interface by using the sub-interfaces. If you set the security level the same for both interfaces then traffic would be allowed to flow between then once allowed by a static command.
For example, devices on vlan1 would use the vlan1 IP address of the pix as their default gateway and the devices on vlan 100 would use the vlan100 ip address of the pix as their default gateway.
Any access restrictions that you require between these two vlans can be configured as access-lists which you apply as inbound filters on each of the two interfaces.
[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
