Internet router firewall settings not working
4.5
Firewall rules are being ignored or not applied.
Symptoms
- Blocked ports remain open
- Invalid traffic allowed
- Settings don't save
Possible Causes
- Rule order conflict
- UPnP bypassing firewall
- DMZ enabled
Step-by-Step Fix
1
Disable DMZ
DMZ bypasses all firewall rules for a specific device.
2
Disable UPnP
UPnP allows apps to open ports automatically, bypassing rules.
3
Check Rule Order
Ensure "Deny" rules are above "Allow" rules.
When to See a Technician
A misconfigured firewall is often worse than no firewall. Use "Default Deny" for best security.
