This is a survey of types of NAT in various equipment.
See NAT and VOIP for more information about the problems with IP-telephony and NAT.
Use STUN clients to test equipment and add your result here using either cone NAT,
restricted cone NAT, port restricted NAT or symmetric NAT (see here for definitions).
