Can anyone recommend a software/hardware firewall for my Dell Poweredge server? I'd like the firewall to protect my hosts as well.

Thanks

Peter

What does the rest of your network look like? Is this for home, or for a business?

steer away from software firewalls, by the time you have done server and clients its more cost effective to buy a hardware firewall

I have a LAN setup at home for practice purposes. I have at the moment a Dell Workstation and a Toshiba laptop connected to my server.

Pete,

The Cisco Pix firewalls vary in price quite considerably. The one I'm looking at in the Misco catalogue is the Cisco Pix 501 at around £249. I take it that this should serve me well, even though it's the cheapest?!!!

Why does everyone think the PIX is the cat's meow? After working with any other enterprise-class firewall, you'll want to kill yourself working with a PIX. Cisco's got the start of something good with the PIX, but six years after buying the PIX product line, they still need to finish it.

If you can afford it, buy a NetScreen-5GT 10-User unit (refurbished or used to save money, if you can find it).

Pete,

Thanks for the advice. Just to double check the setup I want to establish, I will be ditching my Netgear adsl/router for the Linksys adsl/router/4 port switch. So I should be able to connect the Linksys and Cisco PIX together without any conflict?

I'm not Peter but you'll be ditching the NETGEAR router for the PIX itself (or something else, God willing ;). You won't need another router/firewall (like the Linksys BEFSR41 you mentioned) between the network and your ADSL modem. The PIX can be configured as a PPPoE client (or DHCP client), just as the NETGEAR could.

Hi  Peter_Fabri
you could go for a much cheaper option, find an old machine you have at home, p233 64M ram and 1G HD and get any of these Linux  packages " IPcop www.ipcop.org;  smoothwall  www.smoothwall.org ;
clarkconnect  www.clarkconnect.org;  SME(e-smith) server  contribs.org (my preferred fav)"
ipcop and smoothwall are dedicated firewall, while clarkconnect and sme(e-smith) are servers as well.

I use SME at home and a few work offices and know others who use them as part of their businesses and have no regrets ( and it's very very easy to install) you don't need to be a Linux geek to work it out.

hope that helps

Yep i agree with funkusmunkus, I have used both IPcop and smoothwall on several occasions and found both to be excellent, one of the packages he recommends will probably do all you need and be very easy to setup and maintain.  It does really depend on the complexity of your environment and what you are trying to accomplish to make a more specific recommendation.

Its like asking for advise on a computer to buy and not telling us what you plan on doing with it, so if you have any more requirements you can tell us about, that would help.
