Debian ZPH TOS detected with mikrotik

Hello dear, I am slowly losing my mind with this topic. From SQUID frame matches all TOS 0x40 and other sites that I have identified with TOS 0x30. For example:

acl yt dstdomain http://www.youtube.com
tcp_outgoing_tos 0x30 yt
zph_mode tos
zph_local 0x40
zph_parent 0
zph_option 136

I could see that from the debian packages properly marked out and running right mikrotik:

LOG TCPDUMP

14:05:01.202941 IP (tos 0x40, ttl 64, id 5757, offset 0, flags [DF], proto TCP (6), length 52) and 14:14:04.784028 IP (tos 0x30, ttl 64, id 28032, offset 0, flags [DF], proto TCP (6), length 52)

To identify the TOS 0x30 mikrotik no problem, this works well:

chain=postrouting action=mark-packet new-packet-mark=0x30 passthrough=yes dscp=12

But the 0x40 TOS there is no way that you can dial, probe with:

chain=postrouting action=mark-packet new-packet-mark=0x40 passthrough=yes dscp=16

following the logic: if 0x30 (debian) = 12 (mikrotik) then 0x40 (debian) = 16 (mikrotik)

But this does not work, also follow the equivalence of the following thread: http://forum.mikrotik.com/t/new-dscp-tos-value-error/17225/1 (does not work)

Any suggestions? Thank you!
