I have a VM that I would like to do some network experimentation on. Currently it is running Xubuntu 12.04 on VirtualBox but I'd be willing to change that up.
I would like to have 2 network interfaces set up - one that has access to my internal network, and one that has access to external traffic.
The end goal of this would be so that I can throttle external traffic without throttling internal traffic as well.
I used to run a firewall server that functioned like this (Smoothwall) but since this is a device on an internal network I can't wrap my head around how to configure it.
