[c-nsp] setting source address for icmp messages

[Mike]

No.

I am trying to ensure that if the router ever emits icmp messages like 
'destination host unreachable', 'icmp frag needed' and the like, that 
I'm using a public routed ip and not some random flavor of the week ip 
related to whatever interface the router thinks is closer to the problem.
