Hello List,
We have a monitoring app that receives udp packets from units in the

the process of increasing the number of units we have reporting and

somehow route a
copy of each packet to another machine so I can test out different
hardware configurations
to see how performance is affected.
Any ideas on the best way to do this?
If you are using PF as your firewall, you can use dup-to (man pf.conf)
"The dup-to option creates a duplicate of the packet and routes it
like route-to. The original packet gets routed as it normally would."
you can also use netgraph to tunnel a copy of the packets to another
machine.
