I have a point to point network for a branch to my head office. I need to connect it to my Internal Network Switch 3750 port. I have a spare PIX 515E that is not in use. My question is that what will be better choice both security wise and speed wise between PIX 515E and Cisco 3750 switch. Should i make a VLAN in cisco 3750 and let this network communicate with my internal network servers (Exchange 2007, Terminal Server) through access list or connect it to PIX 515E first and then to the switch? The point to point link is connected like this:
Branch CPE > wireless provider > My Head Office CPE.
