Since I upgraded my home m0n0wall (running on ALIX) router to 1.3b14, I am experiencing an issue
with my VOIP provider (Via Talk) that I am assuming is a side effect of the newly added nat source
port randomization. 

My calls get placed or are received, but I cannot hear the remote caller once the call is
established. 

I have worked around this problem temporarily by assigning a static IP to the VOIP device in a 1:1
NAT configuration, but I imagine I am in the minority for having an extra IP available for this
purpose. 

Is it possible to selectively turn off source port randomization for certain IPs? Is my VOIP
provider doing something it shouldn't be? Any thoughts? 

BTW, here is the forum thread I referenced:
