My
linux box has a finicky program (let's call it the "Sender") on it that
refuses to send to 127.0.0.1. However, I have another program running
on that same box that needs to receive the UDP traffic from the
Sender. We'll call that one the "Receiver". These two programs must
reside on the same device.
Is it that it can't send to 127.0.0.1 or is it the loopback interface
that's the problem?
If it's just the IP number then you could use a stub host on a
non-routed network. I.e.
ifconfig lo\:1 10.1.1.1 netmask 255.255.255.255 up
Now, if you can get your Receiver to listen to all the interfaces
including the lo:1 interface and you can get your Sender to talk to
10.1.1.1 then you don't need to use NAT at all.
