    Does anybody know of a good firewall testing program or port scanner (one that can be pointed at a remote machine)?

    Symantec.com has an online port scanning utility if that helps

    You can find an online scanner @ www.grc.com

    edit: that one does not allow you to be at one computer and point it at a different ip.

    Yeah, other people have told me the same thing. Nobody has given any detail, however. What does it do, what platform is it for (windows/linux), etc?

    I'm building new rulesets for my firewall and want to test them and also find out what I'm missing, if anything.

    nessus is great but if you're on a windows machine and don't know UNIX and/or command programs something like Retina from www.eeye.com might be easier. Granted it is not open source nor is it free. They do however have a free trial.

    If you are doing simple port scanning there are a ton of programs out there that you can define a range of ports in and let a scan go.

    How well do you need to test the firewall though? A simple port scan will not necessarily protect you from programs running on non-default ports.

    just a heads up, nmap supposedly won't work on xp sp2 due to removal of raw socket support
