A knowledge base article about My bIT VPS was assigned a private (1918) IP address. Why can't I connect to resources off-campus? provided by the UC Berkeley IT Service Hub - Knowledge Portal
A VPS with a private IP address cannot access resources off campus. Similarly, anyone off campus will not be able to reach the server. The exception is if the user tries to communicate with the server while connected to the campus VPN service and there are firewall in place to allow the traffic.
