I don't have a sonicwall here to test with. The ones that I was referring
to are production units in Schools and Banks in the Midwest, and I was
using iaxcomm (inside) to access asterisk (outside on a registered IP).
In general terms, the customers that have them are very satisfied with
them, but most don't have to deal with their tech support. The state of
South Dakota has standardized on the sonicwall stuff and really have not
had any significant issues (they have had some minor ones though).

We've also configured some of those boxes to port forward (to the inside)
for various functions, but none with udp 4569. Never had any issues other
then making sure another rule isn't higher in the chain doesn't block first.

The majority of those sonicwall boxes have been the larger units intended
for small business use. No experience here with the small entry-level boxes.

Our company does not resell any hardware or software, and we have no 
association with sonicwall whatsoever.
