I am unsure of what you are saying.

All I know is that setting nat=yes has never failed me when nat=no has and
we are talking countless phones and installs.

In the OSI reference model, the "Network" is layer 3, IP.

Call it Network, layer 3, or IP, it is the same.

nat=yes breaks the RFC due to NAT but it gets people talking.  My customers
don't really care for things that don't work.

Thanks,
