    Basically there is a single trunk port connection from the firewall to the switch and the firewall is the gateway for all the vlans.  This forces any inter vlan traffic to be inspected by firewall rules.

    Hi

     

    about the bandwith: depending on the interface you are using, If you use a FastEthernet interface your max Bandwith would be a total of 100Mbit, ( all traffic in different vlans share the same interface). Same counts for a Gigabit interface.. You share the bandwith of that interface with all vlans. Etc Etc

     

    The benefits are cheap! ony need one Port on you switching infra. But this also can be your problem, all vlans share traffic over one port. If you do a lot of traffic congestion will be a bottle neck!

     

    hope this helps a bit
