The short answer: A jump server is an intermediary host you connect to first, then “jump” from to reach private systems across a network boundary.

OpenVPN Access Server replaces the pattern with a self-hosted Zero Trust application broker: users authenticate against your identity provider and get access only to the specific resources they’re authorized for — no intermediary host to pivot through, just a hardened OpenVPN endpo
