You might want to take look at UML (User Mode Linux). I know that for example the OpenSWAN team uses it to test their IPsec implementation on a single PC. They setup 4 UML instances for 4 virtual PCs and connect them via uml_netjig ( if I am not wrong). More details can be found at http://wiki.openswan.org/index.php/UMLTesting.

I am stuck at moment because I dont have many machines to play with. I am wondering is there any tools, which can be used to build a virtual envionment to play with routing and packet filtering on sinple machine. Tools like VMware would not be my choice because I only have 1GHz PIII with 256M memory.
