# Proxy Server

In the context of the Universität Greifswald's technical infrastructure, a **Proxy Server** acts as an intermediary between a client device and external web servers.

## Role in VPN Infrastructure
The proxy server is specifically utilized during an active VPN connection. Its primary function is to allow users to access university-external online publications that require university-authenticated routing.

## Configuration and Implementation
To use the service, users must manually configure their browser's proxy settings using the details for [[proxy-uni-greifswald-de]].

### Mobile Device Constraints
Proxy configuration is generally impractical on mobile operating systems. Consequently, the [[universitatsrechenzentrum-urz]] advises mobile users to rely on the system-level VPN profile rather than browser-level proxy settings.
