When I said "This renders the rules for those applications useles" that was too strong. Sorry about that.
When the "All Applications" rule exists (f.e in Internet Security Configuration) then application rules being made will be placed underneath this rule. When rules are underneath the ""All Applications" they follow the rule set by the "All Applications" rule.
So, to make rules effective they then need to be moved to a place above the "All Application" rule. Often when people run into programs not working according to a rule it is because of this. That is why I am mentioning it.
Thanks for clarifying what you meant. However what you're saying doesn't seem to be what happens on my system. I have the "All Applications" ruleset at the top, which contains one rule to Allow UDP Out to 255.255.255.255 and another rule to Allow IP In/Out from NZ (Network Zone): LAN to NZ: LAN. I still need to create addtional separate rulesets for any applications that I want to be able to access the Internet and these are all below the All Applications rule (and the System, Windows Operating System, Windows System Applications, etc rules).
It also doesn't cause new rules to be created above it. I just tested again by deleting a rule for an application, running the application and allowing access when the Alert appeared and the new rule for the application was created at the top of the list as usual.
You can do that. Traffic to 255.255.255.255 UDP is a socalled broadcast; an application or the OS lets other computers on the LAN know it's there.
Thanks, it did seem necessary but it's good to know why and that it's not a security risk.
The differences are not there because of inherent differences between the Win 7 x86 and x64 platforms. They are the result of different configuration strategies (which may be born because of different programs on the two platforms and because of different standard configurations being used (Internet Security for the one and Proactive Security for the other)).
Talking about two configurations on two different Operating System will be very confusing when they get compared. I would like to suggest to focus on one platform in this topic and start another topic for the other platform.
Yes, sorry for confusing the issue. I just noticed the differences and mentioned it in case it suggested something was wrongly configured on one or the other system. I'll stick to discussing my Win 7 x64 system for now.
Can you write down the rule in detail?
Allow and Log UDP Out from MAC Any to IP 255.255.255.255 Where Source Port is Any and Destination Port is Any
Allow IP Any In/Out from NZ: LAN to NZ: LAN
I would think that the broadcast may be needed for the games to find each other on the LAN.
That makes sense and explains why I needed to add this rule for my games.
