At home/office I have a Draytek 2600 and a Linux based router. I have a
small subnet routed to me from Zen, so I have a "real" DMZ which is where
my office asterisk box is, so remote connections are only a problem for
the remote NAT firewall.

However I have setup boxes for my clients (I sell asterisk based PBX
systems) which are on the inside of their router, and then I port-forward
5060 and 10000 through 20000 to the IP address of the server on the inside
then use the nat=yes and externip= and localnet= statements in sip.conf.
(Also port forward 4569 to the internal asterisk box as that's IAX which
I use to peer boxes together)

When connecting from the outside you may need a STUN sever which will
let the external device (phone/soft phone) work out how to navigate it's
NAT firewall.
