Summary: Problem when using NAT and Subscriptions
Description:
Scenario: Several Snom IP Phones behind a NAT Gateway (no Portforwards
exist).
Everything is working fine but then a NOTIFY goes out from Asterisk to a
Phone, the Phone sends back the ACK (the ACK is definititly seen by
Asterisk) it does not recognize it as the right ACK packet. Thats resulting
in Retransmission of already sent and received Packets.
Tests were made with Asterisk 1.4.13 In the Additional Info you can see:
Retransmission http://bugs.digium.com/view.php?id=3, then the ACK packet but
after that, there's
Retransmission http://bugs.digium.com/view.php?id=4 because it didnt recognize
the ACK successfully.
