Hello Cezar, CA> Hmm, that would become too complicated. There is no other way ? Quick and dirty solution would be to mark packets on Router A by changing the TOS to some known value (iptables/ -t mangle -j TOS --set-tos ..) and filtering by TOS value on Router B (tc/ filter u32 match ip tos .. 0xff).
