Don't put IP address on only one interface unless you are
setting up a brouter[1]. If you want to do firewalling then
add ebtables rules to block traffic; doing firewalling
with addressing won't work because the address won't be accessible 
as you found out.

1. A brouter requires additional ebtables to make packets flow.
