SoftPerfect Personal Firewall: Complete Setup and Best Practices

How to Configure SoftPerfect Personal Firewall for Home and Small Business

1. Preparation

• Download: Get the latest installer from the official SoftPerfect website.
• Backup: Note current network settings and create a system restore point.
• User accounts: Ensure you have an administrator account for installation.

2. Installation and initial setup

1. Run the installer as administrator and follow prompts.
2. Allow the firewall driver to install when Windows prompts.
3. On first run, choose the default profile for home/small office if offered.

3. Define network zones and profiles

• Create profiles: Make at least two profiles — Home (trusted) and Business (more restrictive).
• Assign networks: For each network adapter, assign the appropriate profile (e.g., home Wi‑Fi → Home).

4. Set default rules

• Default inbound: Block all incoming connections by default.
• Default outbound: Allow common outbound traffic (HTTP/HTTPS/DNS/Updates); block unknown or suspicious outbound by default for Business profile.
• Logging: Enable logging for blocked traffic for at least the first week.

5. Create essential allow rules

• Web browsing: Allow outbound TCP ports 80 and 443 to any destination.
• DNS: Allow UDP/TCP port 53 to DNS servers.
• Windows updates: Allow required Microsoft update servers or use the Windows Update service process.
• Email/Calendar apps: Allow specific app executables or ports (SMTP/IMAP/POP/Exchange) as needed.
• Printer and file sharing (Home): Allow SMB and mDNS only on the Home profile and restrict to local LAN addresses (e.g., 192.168.0.0/24).

6. Create essential block rules (Business)

• Block peer-to-peer and torrent ports.
• Block known risky applications by executable name or hash.
• Restrict remote access (RDP/SSH) to specific IPs or VPN subnets only.

7. Application-based rules

• Prefer creating rules by executable path or publisher certificate rather than by port alone.
• For each business-critical app, create explicit allow rules; for unknown apps, block outbound by default.

8. VPN and remote access

• Allow VPN client executables and the specific VPN ports/protocols (e.g., OpenVPN UDP 1194 or IPsec).
• For remote administration, require connection via VPN and restrict management ports to trusted IP addresses.

9. Testing and validation

• Use a separate device on the LAN to test access to shared resources.
• Test outbound web browsing, email sync, updates, and VPN connection.
• Review the firewall log for blocked legitimate traffic and create exceptions as needed.

10. Maintenance and monitoring

• Weekly: Review logs for unusual blocked outbound traffic.
• Monthly: Update rules for new business apps and patch SoftPerfect and OS.
• Incident response: Temporarily enable strict logging and isolate affected machines if compromise is suspected.

11. Example minimal rule set (Home profile)

• Allow outbound: TCP 80, TCP 443, UDP 53
• Allow: Windows Update service (by process)
• Allow LAN: SMB (ports 445/137–139) restricted to 192.168.0.0/24
• Block inbound: All
• Log: Blocked packets

12. Security tips

• Keep the firewall and OS up to date.
• Use least privilege for admin accounts.
• Combine firewall with endpoint antivirus and regular backups.
• Regularly export and securely store firewall configuration.
