2 wan 4 lan mangle portforward local

hi there i meet a problem (i’m newbie)
my current situation is
eth5 (wan: 192.168.1.252) ==> eth 6 (mark routing : wan 2 / 192.168.100.0/24)
eth1 (wan: 192.168.8.252) ==> eth 4 (mark routing : wan 1 / 192.168.12.0/24)
==> eth 2 (mark routing : wan 1 / 192.168.10.0/24)

i want connect eth2 (NAS / 192.168.10.1) to eth4 (switch /192.168.12.254).
i did direct dstnat to 192.168.12.254 to 192.168.10.1 and not working

sorry for my bad english language
