I'm looking for the best way to protect a brand new server installation.
I'll have 2 web and email servers (Windows or Linux) i have not yet decided.
One Blackberry BES 4.1 server. One Exchange 2003 server and one SQL 2005 server.
And last but not the least, one server that will act as a backup server with Blackberry Bes 4.1,
Exchange 2003 and SQL 2005.
All this will be hosted on fiber 100mb isp.
I'd like to know what kind of firewall to use and if the server will have internet ip's or private ip's.
Any suggestions about hardware and software will be appreciate.
