I have 5 (soon to be 8) PowerEdge servers that I want to firewall and have only certain ports (HTML, RDC, FTP) open. Each server has its own IP on the web. Wire comes in, goes to a 3COM switch, then to individual Linksys routers, then to the Servers. I want to eliminate the individual routers and go with a single device for all the servers. What do you recommend keeping in mind that just opening a couple ports is really all we have to do ?
