[Asterisk-Users] Asterisk behind NAT

[Joao Pereira]

Thank you very much
And if I put the correct SRV records in the DNS, can Asterisk receive 
calls??

How does the router knows, that the call must be delivered to Asterisk? 
Can I map all the requests that reach the router port 5060, to be 
delivered in 192.168.0.50 ?

Did someone implemented successfully a SIP domain in Asterisk behind NAT?
Thanks
Joao Pereira
