I am looking for a cheap hardware firewall to sit in front of ISA. I have a belkin 4 port router / firewall ($50) at home and it is soooo close to being what I want. The immediate issues I see is that the virtual servers cannot specify which external IP it is listening on... oh and there is a pretty mean bug that is preventing me from setting the ip properly on the virtual server. Beyond those issues it is highly configurable (and could likely be fixed with a firmware update) and I am looking for something similar. Any suggestions are appreciated...
