Hello, I currently run a bridge with mastershaper but I im having somme issues regarding the udp packets that are fragmented is seems that they are unable to cross the bridge as they should they reach the other side of the network unusable, I have been trying to read regarding this issue on internet but couldn't find any answers. Those udp packets are sent via multicast on the network Im currently running Kernel 2.6.18.3 and bridge utils bridge-utils-1.0.4-4.
