Using 5.6.x, a scenario designed for a public IP now needs to support life in the cloud behind NAT. I'd like to avoid having two listeners to separate on-net from off-net traffic. In a HA scenario, it would be nice to have only one floating IP.
Is it possible to use the same local address and port for external/public and internal/private traffic?
Should set_advertised_address() override the listen advertise address?
Initial testing did not produce the expected result. I want to make sure I'm following a sane pattern before going down a rabbit hole. The idea is to toggle the advertised address by checking if the sender or recipient is rfc1918().
For the dispatcher module, is it possible to use socket names like below? In testing it appeared that only one of the two names was valid.
