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). This Policy will "Loopback" the Users request for access as coming from the Public IP of the WAN and then translate down to the Private IP of the Server. While it's impossible to list every single important port, these common ports are useful to know by heart: 20 - FTP (File Transfer Protocol) 22 - Secure Shell (SSH) 25 - Simple Mail Transfer Protocol (SMTP) 53 - Domain Name System (DNS) 80 - Hypertext Transfer Protocol (HTTP) 110 - Post Office Protocol (POP3) Outbound BWM can be applied to traffic sourced from Trusted and Public zones (such as LAN and DMZ) destined to Untrusted and Encrypted zones (such as WAN and VPN). 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.
