Hi all :))
Sorry for asking again, but got no answers and google doesn't
give useful information (seems like "nexthdr" doesn't work right, but
I don't know why...). I really want to know what am I doing wrong...
This filter matches what I want:
tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\
match ip sport 0x3000 0xf000 flowid 1:22
and traffic goes to 1:22, but this one doesn't match:
tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\
match tcp src 0x3000 0xf000 flowid 1:22
I don't understand why the first one matches and the second one
doesn't :? because in the output of "tc filter show" the only
difference is that the first one matches "at 20" and the second one
"at nexthdr+0", which should be identical :?????
Looks like "nexthdr" is not working, and I prefer to use it just
in case I have to filter IP packets with options (because then the
first filter won't work).
What the heck am I doing wrong? Is iptables my only option?
What's the matter with "nexthdr"?
Thanks a lot in advance :)
