In the weak end system model, yes. In the strong end system model
that does not apply. Some systems (eg HP-UX, perhaps Solaris) allow
the system to be put into (some variation on the theme of) the strong
end system model.
Why would a machine reject a packet:
1) Destined for a non-local address assigned to that machine;
2) That was routed to it by the network; and
3) That is not prohibited by any firewall rule?
Just to break things for the sheer hell of it?
