Good luck man... I wouldn't tolerate my boss looking over my solder. No one can work like that and this isn't something that is going to take 5 minutes.
You will spend time installing, reading references, initial setup, reading more references, configuration, yeap.. more references, testing, tweaking, read why xxx isn't working, tweaking....
That is not the time for "why is it doing that?", "Ok tell me what you just did so I know how to do it", etc...
If I were you, I would ask my boss to leave me to it and once I had it completed I would provide a process on installation, configuration, and then a walk through. For the walk through hook a client pc up to it so he can see how it interacts, logs, etc.
Just be sure to take lots of notes
Also, you definately should be installing it and testing it on your own if you plan on going through with this.
Hearing about someone with a boss like that makes me angry. Frankly, I wouldn't want to be in your shoes when/if it crashes. Running something like a firewall in a production environment with little or no real world experience is a dangerous endeavor. When it goes down you won't have access to the net, nor will you have a tech support number to call for help.
If the company is of any size I would suggest you spend some money on a product with support directly from the maker, such as Astaro. At the very least find a company near you that supports IPCop and contact them about their rates.
When the whole place goes down (it's only a matter of time) you will thank god you did
