Tips

  • Use Caution: Be careful when blocking applications. Blocking essential system processes (like Windows Update) can disrupt system functionality.
  • Virtual Machine Testing: Test SimpleWall in a virtual machine before deploying it on your main system to avoid potential issues.
  • Use with Windows Defender Firewall: SimpleWall works alongside Windows Defender Firewall; you don't need to disable the latter.

Common Mistakes to Avoid

1. Ignoring Rule Creation

Reason: New software or services might not be automatically allowed by SimpleWall, leading to connectivity issues.
Solution: Manually create a new rule to allow the specific program or service through the firewall.

2. Overly Restrictive Rules

Reason: Blocking too much network traffic can prevent legitimate programs from accessing the internet or other network resources, even if they are not malicious.
Solution: Review and simplify overly restrictive rules, starting with allowing necessary programs or services and gradually tightening security if needed.
