Planning to install MS Small Business Server, including Exchange.

Several people have recommended installing a Linux firewall on a old computer.

Comments about your experience or advice would be appreciated.

Well, the thing to remember is Small Business Server comes with a firewall (ISA), so why complicate things by having two firewalls.

Well this is oftem a mattter of opinion. SBS server comes with Microsoft ISA server which is a gui driven stateful inspection firewall. If you do not mind dual homing your SBS server and adding another potential service to the server then SBS/ISA server is OK. I like the other approach by removing ISA server from the SBS server and manage the firewall separately (one less thing on the SBS server to fail). However using a linux box on an old PC is not very practical for a mission critical app like a firewall. IPchanins and Squid are not easy for a novice to configure either, but they do work.

I would opt for a appliance or other solution like a checkpoint if you could afford it. Make sure it supports stateful inspection, packet filtering firewalls like linksys SOHO gateways are not enough.

Is it possible to remove ISA Server from the Small Business Server machine, and install it on another server in the network? I don't think so, but I would be interested to hear if anybody has done it successfully?
