Full Cone - Least restrictive with amount of packets allowed.

Restrictive Cone - Filters based on Source IP Address

Port Restricted NAT - Acts like a restrictive cone but also filters on Port

Symmetric - Port restricted but packets coming from
the same source address and port internal to the NAT, that are going to different
destination addresses and ports are given different external address port mappings.
