asterisk users - Mar 2003 - NAT Troubles (SIP) - 407 Proxy Authentication Required?

I'd like to thank you all for the work that has been done on NAT
SIP support in Asterisk recently. This is truly the sort of project that
proves the strengths of open source development. I noticed that there
were a few people who had NAT SIP working (ATA 186 inside NAT, Asterisk
with public IP), but I for some reason cannot get my ATA186 to register
with my Asterisk box if they are behind NAT (system updated to match CVS
just minutes ago (Tuesday afternoon)).


Here is what my console tells me when the ATA186 tries to register:

 (Log attached)

For some reason, this 407 Proxy Authentication Required seems to be
getting in the way... Any ideas? The UID and PW are fine in the 186 (it
works great when it isn't behind NAT).

Thanks again for all the great support!

I'd like to add that I have seen this same problem using Arrayvox Voxphones
(SIP phones also) both behind and not behind NAT.  Figured it was something
wrong with the phones seeing how they are cheapies ($149 new).  Maybe not.
