That looks correct.

Nonsense -- the last packet that you show in the trace below is a response from
10.100.100.11 back to 172.17.180.71. But it should be returned to 172.16.180.67
rather than 162.17.180.61.

eth0      Link encap:Ethernet  HWaddr 00:E0:7D:A7:0B:BF
         inet addr:172.17.180.67  Bcast:172.17.180.127  Mask:255.255.255.192

Yes -- In your original post, you told me that your internal interface was
172.17.180.64/255.255.255.192 which is 172.17.180.64/26. But I wrote (and you
blindly copied) a masq entry as follows:

        /etc/shorewall/masq
        eth0:10.100.100.11      172.17.180.0/26      172.17.180.67

See the problem?
