The MARKing is not done on the IP packet itself. It MARKs the internal
IP data structure used by the kernel. If you want to mark (note the
lower case notation here as opposed to MARK) you can use the TOS field.

Blagovest,

You are actually desiring to use ToS (Type of Service) markers on the IP 
packet itself.  In order to set ToS, you'll use the -j TOS option to 
iptables.

Good luck,
