My suggestion is to walk away...
I have to agree with this. Tell your main admin and let him handle it. Your port scanning from the outside, with out the admin's permission or knowledge is going to do one of two things; piss your admin off cause he thinks he is being attacked, or cause your IDS system to kick in and shut down every outside port (depending on the ids level of course), going into "protection" type status, which will also piss off your admin.

You are going down a road that will most likly end up with you being fired.

You have had fair warning. We (sys admins) don't like when asshats that work for the company take it upon themselves to start doing penetration testing. Personally this is grounds for immediate firing if I ever catch anyone doing this, and I have caught people both inside the network and outside the network trying this over the years. They no longer work for us.
