Incoming Port Blocks

To provide a more open network inline with the university setting, while still providing some network security, ResNet has re-configured the incoming port blocks.

Any port not listed below remains unblocked (excluding a more general list of ports that are blocked campus-wide). This will allow students who live on campus to do things such as host games on their gaming consoles or their computers, ssh and remote desktop. For public web hosting, we recommend you use your student computing account or an external host.

Thank you for your patience as we try to balance network usability and security. Please contact us if you have any questions regarding this information.

Below is a list of incoming ports that are blocked specifically for ResNet:
