inter vlan routing

sorry for disturbing you. I got a problem with linux and vlans. Would be
great if you could give me some hints so that I can solve my problem.
I want to secure my internal network with linux firewalling using
content filtering. This works - of course - great if i stay in the world
"of layer 3". But if i want to rape my linux box so that the box acts
like a switch it does not work. it is possible for me to configure some
kind of "inter vlan routing" but what i need is "inter vlan switching".
i got two cisco switches in every location offering lots of vlan (w-lan
for voice over ip, w-lan for data, printer stuff, citrix stuff ...).
these switches are communicating with a big cisco catalyst in the main
data center (we got two of them). I want to secure the traffic between
the two switches using linux + content filtering + iptables ... but i am
too stupid to make the switches communicate through the linux box. i can
communicate trough vlans with the linux box. but i can not communicate
with the switch at the other side. i guess this is because the box does
not send the packets for certain vlans to all physical interfaces having
configured the sender (same) vlan (only two one ... maybe the box wants
to route ?)...
would be great if youŽd got some ressources for me to solve my problem
--> learn how to build a linux switch.
thx i advance
