I'm looking for an os router distribution with a very low memory footprint. I want to start it in a VM to join multiple VM subnets together in a lab environment.
Anything that requires that the host os (Windows XP) reboots is not an appropriate solution, for reasons that are out of scope of this question.
I am using freenas as an iscsi target in the vms, and I'm hoping to find something similar to route between subnets easily and simply, and without eating excessive memory.
Alternatively, if there is a commandline or two that I could execute inside freenas to turn it into a router that would be perfect too. It's ok for the guest OSes to have to reboot ;-) but rebooting the host os itself is not possible unfortunately.
