i have problems setting full TOS field in my IP packets i can set only DS variant of TOS (and only 4 types of it anyway, without support for 'stream' and ECN) this is ok for most ISP's but not for all (RFC 791 compiliant ones reqire different TOS as their routers translate it when passing TOS to other networks, and so using such network thru a tunnel could be troublesome)
also TOS<>DS translation engine could be nice when i try to set different TOS it says 'bad tos value'. -- --
