I have a Pix506e and a cisco catylist 1900 en. I want to setup 2 vlans on the pix 1 DMZ and 1 inside but a little unsure of the security implications of doing so. I am new to cisco products and this is part of my home study lab. What is the best/common practice for this design. I also need some guidance with the physical connections of this design as well as the 1900 config.
