I think the problem here is that ebtables only inspects frames arriving on
interfaces associated with a bridge.  As a minimum, I expect you will need
(in addition to the above):

brctl addbr br0
brctl addif br0 eth3
ifconfig br0 0.0.0.0

This is sort of a bridge to nowhere (having only one interface), but I
suspect it may be sufficient for your needs.
