Sveiki,
Yep, it was a problem at the upstream which was seeing the packets
twice and adding them into the pipe twice because of that. There were
no skipto rules at the upstream.

Hi,
I got a firewall with ipfw + dummynet.
system is:
FreeBSD 6.1-RELEASE-p10
table 1 contains 211 IP addresses.
00502 pipe 11 ip from any to table(1) out via rl0
00502 skipto 2000 ip from any to table(1)
and with pipe configured
ipfw -q pipe 11 config mask dst-ip 0xffffffff bw 256Kbit/s
however everybody only getting half of it i.e. 128 Kbits.
also net.inet.ip.fw.one_pass: 1 doesn't seem to work properly since
counters show that skipto rule is being triggered and it should not with
the one_pass activated.
Any clues how to make it give the speed it is supposed to?
