I currently have a small Microsoft SBS network that I want to (1) improve security on (2) install a web server on. I'm thinking of purchasing a Cisco ASA 5505, and was wondering if it could take care of my routing needs. I will have two external IP addresses. One for my SBS server which has my Exchange and one for a seperate web server. Can the Cisco ASA 5505 do this or am I going to need an actual router?
