I would like to know the best and secure way to do that :
PIX2 ethernet 0.1 --> Catalyst 3750 --> Catalyst 4006 --> PIX1 ethernet 1.1
the catalyst 4006 is the VLAN manager both of the pix use subinterfaces
for the moment i configured the interface on the 4006 as trunk but i am not really good with prunning allowed vlans
Can you please give some help ?
