Question about ROUTE --tee

Hi,

I've got a quick question (I hope!) about the ROUTE --tee target.

Does anyone know of any other way to do this - I'm stuck on a Fedora Core 5 box, and find that ipt_ROUTE is not included in Fedora/Redhat kernels.

Essentially I'm looking for any way to duplicate packets and forward them to another box.

thanks
Ramen
