I suspect the fix is somehow to mark the port forwarded packets with
a flag indicating on which interface they arrived at the Linux router,

On the Linux router I can then make sure that appropriately flagged
answer packets go out the correct interface.
Am I on the right track here?
Is the same track I went along a week or so ago and seems to work fine.
Mark them as they come in, then make the PREROUTING table direct them to the appropriate routing table to get back out.
