I just bought my first laptop. It runs Vista, and I need a software firewall to protect both its Ethernet and wifi connections.

I use the free Comodo Personal Firewall on my desktop, but I read that wifi protection requires upgrading to the commercial version.

Before I shell out the money, I'd like to know 1. what the recommended firewalls are for Vista 2. among those, are there free/open-source options?

Thank you.

What do you need that the built-in firewall doesn't do? – Sven Jul 2 '09 at 9:37
What are you using for antivirus? I'd be more concerned about that and just use the built-in firewall. – Russ Warren Jul 2 '09 at 13:14

Windows Firewall and Windows Defender (wich is builtin) is fine.

Just use the firewall Microsoft is shipping. Windows firewall is really ok.

So, you mean it does more than the crappy Windows XP one? That's good news! – Tim Büthe Jul 2 '09 at 19:50

Until Windows included its own built in I used to use Zonealarm, which handles both incoming and outgoing connections. And its free as well.

Do you have any specific requirements. Using the baked-in vista one has the advantage of letting windows installer open ports when a vista aware application requires them.

If you want fine-grained control you could use ipsec? start->run->secpol.msc, then go to the bottom one in the list (IP Security Policies). I've managed to lock myself out of remote machines regularly with that one, so I guess that should suffice? ;-)
