After reading some advice given here previously, I'm looking at a hardware firewall for one or more colocated servers. It seems I also need a switch as each server typically requires three ports, one for the remote access controller, and one each for dual NICs. After some research I found the Sonicwall Pro 1260 device: http://www.sonicwall.com/products/pro1260.html It integrates a 24 port switch with a firewall all in a 1u package which looks pretty much ideal and is a bargain at around £675 + VAT. It gets good reviews and seems to be only limited by its throughput but as I'm only on a 10Mb line it's hardly important. Before I go ahead and purchase one the question is, has anyone got any good/bad experience of these firewalls ?
