Ok here is an even simpler case (mspiggy is a Windows 2003 Server):
% ipfw pipe 1 config bw 6500KBytes/s
% ipfw add 200 pipe 1 ip from mspiggy to mi
Not even pings come back to the ping program, even though tcpdump (on mi)
shows them returning to the kernel:
01:52:23.665065 IP mi > mspiggy: ICMP echo request, id 42518, seq 14,
length 64
01:52:23.665359 IP mspiggy > mi: ICMP echo reply, id 42518, seq 14,
length 64
[...]
This seems to first hit, when I try a fractional number of MBytes:
% ipfw pipe 1 config bw 6.5MBytes/s
Trying to correct it afterwards does not seem to have an effect. The pipe must
be recreated:
% ipfw pipe 1 delete
% ipfw pipe 1 config bw 6500KBytes/s
And then everything starts working again. Yours,
-mi
