I am planning on setting up a Minecraft server in the near future. I would like to also isolate it from the rest of my network, something like this: I have a Cisco DP3825 from Rogers that I am using and a Linksys WRT54G that is collecting dust and I believe both have some form of basic firewall. My brother recommended getting the Cisco ASA5505 (on sale right now) and using it instead of the setup above. My questions are: 1. Can I do this with the routers I have? 2. Would I be better off going with a Cisco ASA5505?
