What is IPsec?

IPsec (Internet Protocol Security) is a security protocol that provides encryption and authentication over the Internet. At Indiana University, IPsec provides a means for users at IU Bloomington and IUPUI to connect directly to the IU network over wireless connections or from remote (i.e., off-campus) locations through a virtual private network (VPN).

Note: At Indiana University Bloomington and IUPUI, you can access the wireless network without using VPN. See What is IU Secure?

Note: A new service, SSL VPN, replaces Indiana University's IPsec- or PPTP-based VPN service. See At IU, what is the SSL VPN service and how do I connect? On July 13, 2009, UITS will retire the PPTP VPN servers; while the IPsec VPN servers will remain available, UITS recommends switching to SSL VPN if your campus supports it.

Operating systems with IPsec support

The operating systems that natively support IPsec VPN connections are:

Third-party VPN clients are also available from various companies on the Internet.

Note: Although Windows 2000 technically supports the IPsec protocol, setting it up is a lengthy process that requires editing the registry. Contact your campus Support Center for help.

For PDAs, Microsoft's Windows Mobile 6.0, 5.0, and 2003 are the only operating systems known by UITS to possess native IPsec support. PocketPC 2002 and Palm OS require third-party VPN clients. For information regarding any other PDA operating system, consult the manufacturer's documentation.

Settings information

Specific configuration instructions are unique to each platform and operating system, but the following settings are required by all configurations:

  Campus   IPsec VPN server name
  IUB   ipsec.indiana.edu
