Murphy,
Unfortunately this patch does not actually change the ToS bits in the ip
packet. Sorry I should have confirmed that before I told you it worked. I
just checkout a fresh copy of nox destiny and confirmed this with wireshark.
(I assumed it worked before, because of this "68, n_packets=37,
n_bytes=3626,
idle_timeout=15,hard_timeout=0,dl_dst=00:22:fa:62:4a:de,actions=*mod_nw_tos:
*0x16,mod_dl_dst:00:17:df:2b:08:00,mod_nw_dst:130.127.39.173,IN_PORT" action
being installed)
Sorry,
Aaron
