GRC Shields Up says this port is stealth.
Foward rule is Enable, TCP, Single Port 3588, WAN 1, Server IP Address 192.168.1.178
Firewall rule is Enable, WAN Connection Any, Protocol TCP, Source Any Address, Single Port 3588
Destination Any Address, Single Port 3000, Action Allow, Event Logging Enable
I can ping the WAN address successfully, but the port is closed.
nc -zv WAN.address 3588
What am I doing wrong?
