What is everyone using for a firewall?
I'm currently using www.astaro.com but their recent releases have soured me on ASL as a practical solution on my hardware (1.2MHz Athlon, 30G, and 256M). I only have 4 computers going through the firewall wall but it's consistently at 50% cpu load. There is very little network traffic (<10k bits per second on the wan connection, < 40k bits per second between other internal lans (I have 4 internal lans and a wan))
Basically I'm using it for:
packet filtering, masq, port forwarding, IDS, dns proxy (only if my internal DNS servers have failed) smtp proxy smtp virus protection smtp spam protection http proxy (caching) http virus protection http url monitoring (via Cobain) the firewall also monitors a bunch of statistics, etc.
I'm looking for something that is installed, configured and runs. I don't want to be tweaking this parameter of postfix, that parameter of the smtp virus protection, etc. I want something that just works that I don't need to play with except for new rules, etc.
I'll pay a reasonable price for a package that I can test to verify suitable performance (I'm not a commercial operation, this is just for my toys).
At the moment, I'm looking at Gibraltar. But the community seems small. I haven't downloaded it yet but I'm considering it an option for this round of firewall evaluation. Any other suggestions for inclusion?
BTW, anything like smoothwall that allows wide open outbound connections and doesn't support a box with 5 network cards off the CD is not a viable candidate.
Thanks much all,
