I just recently upgraded to Windows 64-Bit and I'd like to know if there are any good 64-bit firewalls out there. I'm currently using AVG 7.0 but the problem is that since I have several network adapters it says that the firewall is functioning properly because of a problem with packet filtration on multiple network adapters. So, any suggestions? Thanks in advance.
Well, then you should think about your concept again.
Windows Firewall is a host-based packet filter. As it does not know about the Nat states of Windows ICS, it obviously isn't suitable as a firewall.
Anyway, it does scan outbound traffic. Of course, since it has to capture the relevant states to allow related inbound traffic. I guess you meant that one cannot disable and/or expand the internal ruleset that is applied, which is, well, merely interesting, as one would have to add such a rule anyway.
At first, think wisely if you actually need any firewall. Most likely you don't. If you really do, then think about your requirements, policies and available resources. At least you should understand the difference between a firewall (which is a concept to separate network segments with different trust levels at a perimeter) and host-based packet filters (where there isn't anything to separate anymore).
You router is a router. It might have a packet filter included, which is written in software. It's only hardware as far it's implemented on a dedicated hardware and might, most likely doesn't, include hardware acceleration for some operation.
In replacement for a real, serious firewall? Most likely not. Implementations on common consumer-class routers are usually so fucked up...

He states that he wants something similar to ZoneAlarm, an application aware firewall. I guess Vista will have such an animal included when it's released in a few weeks.
