Called Optimum and the customer service rep who boasted several years of experience with the company in multiple departments didn't know how to troubleshoot connectivity between 2 sites. This guy saw the configuration i made on the router for a previous project and told me it was that. and that i should open up "the ports", and enable port triggering and put my computer in the DMZ. I mean the more he talked is the more he revealed his ignorance to technology. I proved to him that the issue wasn't the router by having him try to connect, it didn't work for him either and he still wrapped up the call with telling me to make all sort of unnecessary changes to the router. What if someone had actually listened to this guy and got hacked?
