Re: What is Symmetric NAT? |

Greetings Paul,
There are several types of NATs, based upon how exactly the "NAT" operations are being
performed. A symmetric NAT is one in which all requests from the same internal IP and port
to a specific destination are mapped to the esame external IP address and port.
In MSN Messenger 6.1 and above (not sure if 7 changes any of this yet), for features that
require a direct connection (to either work or work well) Symmetric NATs are not supported
unless they support UPnP.
