![]() Also, if you are trying to gain access to MathSciNet, go to and look for "Univ of Calif, Los Angeles" in the top right of the page. Go to and confirm that your IP address matches the host IP that you are tunneling through.Ģ. Make sure 'SOCKS v5' is selected and select the 'OK' button to save.Īs long as your PuTTY SSH connection remains connected, your proxy tunnel will be open and you will be able to use the internet through this proxy.ġ.

The hostname should be your UCLA homesite followed by ".". Things you'll need: A Linux Mathnet account, PuTTY (ssh client), and Firefox.ġ. This example shows a connection from a Windows machine using Firefox. A proxy setup can be configured using OSX, Linux, or Windows using various browsers. If you are browsing this site from off-campus, and you have a Mathnet Linux account, you can use this proxy setup to make it appear that your traffic comes from one of our IP addresses.
