I run a small web building/serving company (300 sites, lightish traffic) off a few XServes and 6 older machines happily off a T1. I just picked up a client who will be flinging me into the 100Mbps fibre arena with business related video streaming.
I use software (ipfw) on the Xserves, and a small SOHO DLink as my current firewall protection for other servers and internal network, and I feel the need to set up an independent gateway firewall to secure the network.
I have about $4000USD to spend, however, I plan to spend half of this on a managed switch (3com 24-port managed gigabit) to make sure my existing clients don't get squeezed out of bandwidth by this new client. If there is a managed GB switch that includes FW protection, I don't know about it though.
I see, from reading questions here, that there are a number of expensive solutions out there (Cisco PIX and Symantec SGS seem to be the winners). Ideally, as I am running Mac only, I would like a web interface for the firewall, not wintel GUIs. I would also like it to just plug in and have it secure the network immediately, although I am willing to do what it takes to get things working (time constraints of a small business and all).
In an ideal world, I would buy another second-hand XServe and have it run some kind of gateway firewall protection. Then I would have all necessary hardware handy in case of failure, and existing infastucture to mount/support them.
I am pretty lost though, and need advice.
a) Can I use an XServe as a stand-alone gateway firewall?
b) Should I buy a Cisco PIX or a Watchguard instead? Their pricing structure is impossible to figure out. What is the most inexpensive firewall solution I can get to service my needs?
Thanks for the info
