Hi all, After reading a lot and searching on the INternet, I want to filter ASP and/or AH traffic According to /etc/protocols ESP and AH are IP protos 50 and 51 so this u32 filter should work ? (I can use fw filter because the firewall/VPN can't mark pakets :-( tc filter add dev ethX parent X:0 protocol ip prio X u32 match ip protocol 50 0xff flowid X:XX ? Can someone confirm this ? Many thanks G.
