The tool "looper-ng" was pointed out to me and is working really well for
this task.

It can't pass the trap to Ciscoworks, unless ciscoworks can listen on a
non-standard port. The it would work just like the other destinations - use the
forward token in your snmptrapd.conf. As fare as the source IP, there was a
recent thread on that here (or on the coders list), but I wasn't following it.

It wouldn't be to hard to write a small app that reads incoming packets to port
162 and simply redirects them to 4 other destinations. The source IP in the
packet's IP header would change, but if the remote destinations get the trap
address from the trap, instead of the IP header, you should be ok.

You are lost in a twisty maze of little standards, all different.
