Thanks for attaching the capture files so I can view them in easily in 
Wireshark :) and sorry for the delay in getting back to you.  Don't 
worry about the bad checksums, those are on TCP packets that we aren't 
concerned about in this ping issue.  To make it easier to troubleshoot 
this issue, type "icmp" and hit enter in the Filter field in the top of 
Wireshark so it shows only icmp (ping) traffic.  Then you can more 
easily see that the captures show the 5 ping requests 
leaving 192.168.1.100 and entering 192.168.1.64 and .64 does not send 
out a response.  Which IP belongs to M1 and which to M2?
