Basically what would happen in these nstances is that in Twinkle's twinkle.log file, I'd see packets going from my laptop (192.168.1.44), back to 192.168.1.44 even though my Asterisk I was trying to reach is at 192.168.1.43. For this reason, even though at the Twinkle CLI I'd type call sip:300@192.168.1.43 (a test extension I have here), I just get put back at a "twinkle>" prompt with no discernible activity occurring at the console.
