I have a WiFi router hidden so we can do some specific network testing. We also have a consumer DSL line so we can test on a network where IT doesn’t block random stuff. It’s not even much of a secret. Everybody local knows this stuff and every six months a guy at IT headquarters throws a fit, doesn’t provide an alternative and gets ignored. I have thought about sending them recordings of previous meetings so we don’t have to repeat the series of same meetings every six to twelve months.
