One of my suitemates across the hall is on the same network as me and is being a jerk about using up all the bandwidth. He is using limewire and it boggs down my bandwidth badly. im wondering if there is any way that i can limit the ingoing/outgoing bandwidth that he is using? what im looking for is a way to block the ports that limewire mainly uses but i only know how to block ports with a router. and i dont think sneaking into his room and instaling a software firewall that blocks those ports is an option. any help would be great.
