SER has been originally designed to forward UDP requests on the same
interface it received them. This didn't work in some multihomed scenarios,
like natted environments or in cases like this. I introduced the mhomed hack 
which leverages IP routing through a temporary UDP socket connect to determine 
proper outbound interface. (We need to know it to be able to print appropriate
IP in Via.) It is optional because some people think it is a horrible hack.
