I am attempting to use ipfw and dummynet to instrument some network traffic tests. I am running freebsd 4.3 release and have built the kernel with ipfirewall, dummynet, and default to enabled. For a simple test, I added a pipe "ipfw add pipe 1 icmp from any to any". When I ping this machine, I can do "ipfw pipe 1 show" and watch the counters increment, but the machine doing the pinging does not see a response to the ping. That's my first question. Next, when I try to delete the pipe, "ipfw pipe 1 delete", it won't delete. The only way I can get rid of it is to do a flush. That's the second question. Third question, if I type "ipfw pipe 1 config bw 10Bytes/s", I would expect the bw to be limited and the counters to reflect this limit. The counters indicate no change in the 64 byte/s generated by my windows client. I have read the man pages for ipfw, dummynet, and ipfirewall. If these are obvious questions, I would appreciate a pointer to a good reference. Thanks -- Logically speaking, logic is not the answer.
