We provide open Internet access to users. The only current security device on the network is a Proxy Server to prevent access to certain websites. Our network is simple:
RF Antennae --> RF Modem --> Cisco 3845(NAT) --> L3 Switches (Core Services) --> L3/L2 Switches --> Users.
Where should I put the ASA 5550 and why? The customer requires this device to prevent traffic initiated from outside the network. From reading the documentation, using the default security levels would be fine and no additional ACL's would be required. I do plan on using the ASA to block any websites or networks that the Proxy can't.
Thanks in advance,
