I would again double-check that rp_filter is disabled.  Changes were made in
kernel version 2.6.31 regarding how rp_filter settings were calculated.  That
seems right around the time you started seeing the issue in your tests.
Make sure you check default, all, and the specific interfaces under
/proc/sys/net/ipv4/
Set them all to 0 for testing.

I had a very similar issue as you (although my setup was much simpler: 1 DNAT
only, no CONNMARK) and some rp_filter changes fixed the problem for me.
