[Asterisk-Users] NAT type router database?

[Thilo Salmon]

Is anybody aware of a database containing the types of nat
implementation in todays soho/consumer routers? I think it would make
sense for the community to have this database in order to avoid
symmetric nats. 

If one such thing does not exist how about starting this database? 
A stunclient for linux can be found at
http://sourceforge.net/projects/stun/

I can contribute this information for two routers:

W-Linx MB400-X2: coned NAT
D-Link DI-604:   coned NAT
