Re: Router trick - how to allow only one single packet

What about VACL's or MACL's? You could block this at the layer 2 frame.

Router trick - how to allow only one single packet

Hi all,

I am trying to
test a client application in the lab and need a method
to block subsequent
requests to a server. The retries (UDP packets
with same length, port number)
etc. from this client should not reach
the server. The retries occur less
than a second later and continue.

Limiting by CAR would still pass some of
the requests a few seconds
later. I can't record and spoof this first packet
because of the
encoding in the packet.

I was also thinking of load balancing
by packet and creating numerous
sinkholes at dummy destinations.

Any ideas or
EEM?

Thanks
Rich
