Abrir Puertos Firewall Windows 11 Verified 90%

Several issues often arise. First, a user may open a port in Windows Firewall but forget that their home router also has a firewall. In such cases, port forwarding must be configured on the router’s administrative interface. Second, a third-party antivirus suite (e.g., Norton, McAfee) may have its own firewall that overrides Windows settings. Third, opening a port that a system service already uses (e.g., port 445 for SMB) can cause conflicts or security vulnerabilities.
