CSE Network Blocking
CSE imposes a firewall over most computers in CSE that blocks almost all ports for external computers.
If you have a registered computer at CSE then you can open selected ports using CSE's User Firewall controls.
It is generally better to leave your computer blocked from the outside world and access it over a VPN connection.
