An example creating a 20 second delay.

# ipfw pipe 10 config delay 9999

Now we create a couple of firewall rules. I will give this “royal treatment” to betweeen “pinger” and “pingee”

# ipfw add 121 pipe 10 icmp from x.y.z.t to me
# ipfw add 122 pipe 10 icmp from me to x.y.z.t

(Adding delay to both the ping and the ping ack so that the maximum delay I can get is 20000 ms)


And testing:

64 bytes from a.b.c.d: icmp_seq=259 ttl=60 time=20000.069 ms


If you need it, give me the IP addresses from which you intend to do the tests and the delay you need and I can create a
ping target on my test server in Amazon’s EC2.


Cheers,





Borja.
