Yep, like I said you make it out to be a big deal. The STUN server
took about 5mins to set up and it runs and runs and runs. The
telephone is configured to enable STUN when it's provisioned. NAT
is a fact of life, likely will be for quite some time to come. When
everyone has public addresses, we can stop the STUN server, woohoo.

Well, it is a blocker if /I/ want to play with asterisk at home.

Assuming "at home" = on a private address, behind a router with NAT.
Assuming "to play" = make and receive VoIP calls with SIP.

You can run asterisk just as you can run a webserver, a mailserver, a
VPN or a NAS at home, on your dynamic address. You will need a dynamic
DNS service, but that's not a problem. You will need some port
forwarding, also not a problem. For your external SIP clients, you
could run a STUN server, also not a problem, or you could ask them to
enable keep-alive.

It's entirely doable, Carlos. That you're on a network behind a NAT
router does make it more difficult, but only slightly.
