Ticket #351 (Invalid) changed by Mike Jagdis - aliased interface

This seems entirely correct to me. UDP is not session based. If you do not bind the alias address specifically but use a general 0.0.0.0 then outgoing packets will also source from 0.0.0.0 and this will be replaced with the primary address of the interface as packets go out. Maybe you should bind a socket on the alias address? Maybe you should use “iproute … src …” for some paths?
