[Asterisk-Users] Asterisk behind NAT

[Andre Ruiz]

Kerry Garrison said exactly that three messages before in this thread.

You need to map 5060 and all the RTP ports (10000 to 20000 unless you
changed that).

BTW, Giridhar said two messages before that you should set nat=yes in
sip.conf. Notice that this is for when the *peer* is behind nat and
reaches asterisk outside nat. It will not help when asterisk is inside
nat and being reached from outside.
