Safari 6 (OS X Mountain Lion): Set up a proxy server
If your computer connects to the Internet through a network protected by a firewall, you may need to specify a proxy server to get to webpages and other Internet resources. The server is called a “proxy” because Safari sends requests for webpages to the server instead of directly to the website.
Before you begin, ask your network administrator to tell you which type of proxy server to specify (for example, a web proxy server), the IP address or DNS name for the server, and a port number.
- Open Safari if it is not already open.
- Choose Safari > Preferences, and then click Advanced.
- Click Change Settings.
The Network pane of System Preferences opens.
- Use the information you got from your network administrator to change the proxy settings.
- Click OK.
