Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.3

Hello

 

I made GRC ShieldsUp Test and port 139 is closed not stealth. ER605 HW v2.20 latest firmware 2.3.3.

Is it normal? firewall > attack defense "Block TCP Scan (Stealth FIN/Xmas/Null)" is enabled and "Block TCP Scan with RST" is disabled.

Everything else in FireWall section is default. No port forwarding.

 

Thank you for explanation.

A port in a "Closed" state is effectively the same as being "Stealth" and does not pose a security risk.

OK but...

Attention

Please make sure the "Block TCP Scan with RST" is disabled (you can find it at Firewall > Attack Defense) to get full stealth results.

 

Has anything changed?

Thank you
