[SR-Users] dispatcher behind NAT - lost ACK

[Ovidiu Sas]

The issue here is that your carrier is detecting you as a NATed client
and this breaks your ACK routing.

I overloaded the meaning of interfaces.  Two sockets (same IP,
different ports) works fine in a multihomed setting.
One socket for internal traffic and one socket (with external
advertised IP) for external traffic.
