Send copies of (UDP) datagrams to multiple receivers

Hi,

It would be awesome if Mikrotik could add a support for this feature in its OS: http://code.google.com/p/samplicator/
That would help in cases where monitoring/backup is needed using remote machine(s).

"This simple program listens for UDP datagrams on a network port, and sends copies of these datagrams on to a set of destinations. Optionally, it can perform sampling, i.e. rather than forwarding every packet, forward only 1 in N. Another option is that it can "spoof" the IP source address, so that the copies appear to come from the original source, rather than the relay. Currently only supports IPv4.

It can been used to distribute e.g. Netflow packets, SNMP traps (but not informs), or Syslog messages to multiple receivers."

Thanks.

If you need that immediately, why don't you just bind your NMS stations to multicast addresses? You're essentially describing multicast, and all your examples are UDP based (and it's hard to see how TCP could ever work with that).
