SonicOS Enhanced 4.0 Administrator Guide
Never blacklist WAN machines – This checkbox ensures that systems on the WAN are never
added to the SYN Blacklist. This option is recommended as leaving it unchecked may interrupt
traffic to and from the firewall’s WAN ports.
Always allow SonicWALL management traffic – This checkbox causes IP traffic from a
blacklisted device targeting the firewall’s WAN IP addresses to not be filtered. This allows
management traffic, and routing protocols to maintain connectivity through a blacklisted device.
