If two private parties are connected to the ISP via a router acting as DHCP
of the same non routable Subnet i.g. 192.168.0.0 255.255.255.0

then each private party ISP HOST would get an IP of 192.168.x.x

and if in turn had clients on their HOST that were issued IP numbers from
the ICS Masquerading DHCP sever and simulated hiden gateway that would also
issue from the same IP set,

and the File and print Sharing was enabled on the HOST NIC to ISP Router (a
nomal way to share if one party owns all connections.)

then Party A could block incoming File and Print Sharing ports to his
section of the 192 subnet while viewing, retriving, WRITING, DELETING, and
ADDING to any share of Party B with permissions for everyone.

Dorme, Boarding houses, WIFI areas should not use ICS while sharing a router
ISP connection until their intranet section is secure.

Use another private router and assign an IP for the HOST. Use another
Gateway FW to use another subnet IP set.

OK, prove me wrong.
