When using the filter "(ip.dst == 172.16.0.0/12) && (ip.src == 172.16.0.0/12)" 

If leaves in ICMP traffic with a destination of 10.0.x.x. 

I have confirmed this behavier with multiple sniffs, and with a co-worker who
double checked my logic.

A attachment shows some sample data left behind that should have been filtered
out by the filter. Sorry I can't send you the orgional file.

Bug has been in several versions.

Thanks for the great software.
