Without meaning to start a war, it's my understanding that m0n0wall is regarded as the best firewall on a stick. If memory serves, it's also argued that IPcop is, but it may be that my memory is faulty and the 'top' two are something else. Regardless, the presentation can affirm or correct this.
Preferably within/under VMware ...
- baseline: m0n0wall as firewall between internal and external machines.
- demonstrate DMZ, i.e. rules between external and DMZ, and DMZ and internal.
- demonstrate internal-only control.
