The UCT perimeter firewall protects the network against malicious attacks by unauthorised internet traffic. Specific rules (which need to be applied for) allow access for certain permitted traffic into the network. These firewall rules are implemented as per the UCT Perimeter Firewall policy.
These lists show the ports that are currently blocked on the firewall. For information on how to apply to have a port unblocked, please read more about the UCT Perimeter Firewall.
NOTE:
We will endeavour to maintain this web page, however these lists may not always reflect the latest information.
