Network Address Translation on U of M Wireless

Mon, 27 Jul 2009 15:45:23 CDT | link

Due to the rapid expansion of the University of Minnesota’s wireless network and the decreasing supply of unallocated IP addresses, the Office of Information Technology is planning to change the addressing scheme on the University’s wireless network.

On August 15, 2009, OIT plans to deploy a technology on the “UofM” SSID called Network Address Translation (NAT). NAT is a technology that translates an end user’s private IP address to a public IP address, thus reducing the University’s need for IP addresses.

Once this technology is deployed certain applications that require the user to have a unique IP address may not function properly. One example of a type of application that might be affected is outside VPN clients. OIT expects this process to be completely transparent for most general wireless internet users.

If you experience any problems running an application over the “UofM” SSID after August 15, you can check to see if your application is affected by NAT, or you can switch to the “UofM Secure” SSID, which will not be affected by this transition.

For more information about NAT, visit http://en.wikipedia.org/wiki/Network_address_translation.

If you have any questions, contact wireless@lists.umn.edu .
