AOS provides two remote methods of connecting to the AOS network: a [Virtual Private Network (](https://en.wikipedia.org/wiki/Virtual_private_network)[VPN)](https://en.wikipedia.org/wiki/Virtual_private_network) + MFA (DUO) and an [SSH Gateway](https://en.wikipedia.org/wiki/Tunneling_protocol#Secure_Shell_tunneling).
You can use the [UCLA Proxy Server](https://it.ucla.edu/it-support-center/services/proxy-server). If you only need to connect to the UCLA network to access library resources (academic journal subscriptions).

## SSH Gateway
You may connect to our SSH gateway to access the AOS network if all you need to use can be run from a terminal. SSH to **mercury.atmos.ucla.edu** with your AOS ID, then connect to a subsequent server(s) as needed. SSH Gateway connections will also require Duo Authentication.
