TCP 443 v15+: HTTPs port of Web Server. Let the professionals handle it. 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 total number of instances any device has been placed on Clickon Add buttonandcreate two address objectsone forServer IPon VPNand another forPublic IPof the server: Step 2: Defining the NAT policy. Bonus Flashback: March 3, 1969: Apollo 9 launched (Read more HERE.) The responder then sends a SYN/ACK packet acknowledging the received sequence by sending an ACK equal to SEQi+1 and a random, 32-bit sequence number (SEQr). it does not make sense - check if the IP is really configured on one of the firewall interfaces or subnets.. also you need to check if you have a NAT 1:1 for any specific server inside - those ports could be from another host.. ow and the last thing what is the Nmap command you've been using for this test? Its important to understand what Sonicwall allows in and out.
