📎 AI Summary:
The thread discusses the default behavior of Windows 7’s firewall when it is disabled or corrupt, questioning whether it allows or blocks file sharing requests from LAN computers. The consensus suggests that, by default, the firewall blocks incoming connections unless explicitly allowed, and enabling it with appropriate settings is necessary to permit file sharing. Additionally, to facilitate communication between newer and older Windows systems, users recommend disabling IPv6 and configuring static IP addresses with port forwarding.

Assume I have a Windows 7 system.
The Firewall is completely disabled or corrupt.

So when another computer in (Private Workgroup) LAN tries to connect to this Windows 7 system what should happen?

Is the default (e.g. for File Sharing) ALLOW ALL or BLOCK ALL File Sharing requests from other computers (in LAN)?

In other words: Is the built-in Firewall a tool to open incoming ports (from default blocked) or to block them (from default open)?

the default is block all unless the other computer is newer than Windows 7 i.e, 11 for example

if you want a default of allow then you need to turn the firewall on and set everyone but workgroups are finished

p.s, want new Windows systems to talk to old systems = disable ipv6 from our ethernet adapters, because they use microsoft vpn by default
then set a static ip address to forward ports to
