I check the firewall and we dont have any of those ports open. First, click the Firewall option in the left sidebar. Usually tarpits are internal hidden among the servers, so they look like legitimate unprotected systems, but they're reporting any connections (since all legit connections should know where to go, and thus, never end up at the tarpit's IP) to the cybersecurity response team.. though, in the case of a sonicwall, I guess that would just clutter up the logs really well. assuming it's a logged event. Selectthe type of viewin theView Stylesection andgo toWANtoVPNaccess rules. To accomplish this the SonicWall needs a Firewall Access Rule to allow the traffic from the public Internet to the internal network as well as a Network Address Translation (NAT) Policy to direct the traffic to the correct device.

Note the two options in the section: Suggested value calculated from gathered statistics When you set the attack thresholds correctly, normal traffic flow produces few attack warnings, but the same thresholds detect and deflect attacks before they result in serious network degradation. Usually this is done intentionally as a "tarpit", which is where a system will provide positive feedback on just about every port, causes nmap to be useless (since you don't get an accurate scan of what's open or not) and makes actually probing anything take a really long time, since you don't know if you're connected to the tarpit or an actual service. The device gathers statistics on WAN TCP connections, keeping track of the maximum and average maximum and incomplete WAN connections per second.
