Firewall / Security

Ok lets expand on that a little...

What firewalls do people run here?

I'm currently using a netgear FVX538, which is quite nice but a little limited in places.. I'm looking at a virtual appliance firewall to help augment it.

I've just tried Untangle which looks real nice but in order to get the good features you have to pay a monthly fee.

Anyone have other ones they like?
