if i configure the 4507 with a ethernet module 3 with 48 port into 3 vlans , and give two vlans an management ip and one vlan without ip.The vlan without management ip i named it as vlan-outside .In outside valn vlan i want to connect the pix, dsl ethenet link, and a access rotuers ethernet interface.
i there any posibility that the 4507 get haked since the ethernet of the DSL is plugged in the switch instead of the pix.
i have attachend the powerpoint diagram with this
