Issue/Question

  • What are the client IP ranges for the OSU VPN?

Environment

  • Oregon State University
  • VPN
  • IT Pros, service owners

Explanation

This article is intended for anyone who has IP-restricted a service or device and needs to know the IP ranges of VPN users. This article assumes an understanding of CIDR notation.

When clients connect to the VPN server, they appear to come from an OSU IP address in a specific range. Service or device owners may wish to grant access to this range in their access control lists or firewalls.

Resolution

To grant access to all clients connected to the OSU VPN, allow the following range:

VPN IP Block: 10.197.128.0 / 17 (128.193.152.192 / 26)

Note: on-campus devices will see the private 10. addresses; off-campus devices will see the public 128.193 addresses.

The following table details the IP ranges for each VPN connection type:

NAT Range Pool Pool Block
128.193.152.192 / 28 SAML Full Tunnel 10.197.128.0 / 19
128.193.152.208 / 28 SAML Split Tunnel 10.197.160.0 / 19
