On a linux box 'A' which has interfaces eth0, eth1, eth2, eth3, I would

I would like these packets be unconditionaly redirected unmodified for
output via interface eth1.

That is:
- even if they were targeted (destination IP) at my box 'A', they will
be re-emitted through eth1.
- even if they would have been forwarded through eth2 or eth3, they
will be re-emitted through eth1 too.

If they would be forwarded anyway, advanced routing can be used to
force them out a specific interface.

For packets whose destination is 'A', I think you would need to do
something with netfilter to get the packets on to the forwarding
chain, but I don't know how without changing the destination IP
address.
