Playing at work.

[murcielago200]

So I was playing EQ at work and IT happened to walk by and we got to chatting and he used to play EQ back in the day "oh that game ruined my second marriage".
I mentioned I'm having to make my phone a hotspot to play at work and he said oh I'll just unblock it.

What info do I need to give him so he can unblock it? What ports or ip or what?
Why would it be flagged as something to be blocked? He said he does other mmos at work and they are not blocked.

I meet with him in 8 hours to tell him the info.
