I need some help on selection of the firewall. My situation is like this: I have one Web Application Server and a Database Server (which supports the web server). Now I need a firewall hardware to have the following features:
1)switch: so that I can connect both the web server and the database server to it;
2)DMZ: so that I can plug in a caching server.
3)VPN: so that I can use my PC remotely access the web and database servers. (My PC will be installed the VPN CLient software).
Which firewall product(s) should I choose?
As for the DMZ, do I need to purchase the additional/external card to plug into the firewall equipment OR it has already built it in?
Many Thanks.
Scott
