In case your Mac connects to the local network which is protected by a firewall from accessing the Internet, you should either get the proxy servers specified or use the passive mode of FTP (PASV), to have access to some websites. A proxy server is a term for a computer on your local network which works as a mediator between the Internet and a single user of a computer. This way the network will ensure administrative control, caching service, and overall security.
Configure Proxy Server Settings
- Launch Apple menu, then go to System Preferences, and open the section Network.
- In a list that opens select your actual network service – for instance, Wi-Fi or Ethernet.
- Click on Advanced, and then go to Proxies.
- If you get the settings of the proxy server configured automatically, you should enable Auto Proxy Discovery to discover the proxy servers automatically. In case you are using PAC file (proxy autoconfiguration), you can enable Automatic Proxy Configuration. If you choose Automatic Proxy Configuration, you should type in the PAC file address into the field of URL. To get extra information, request it from the administrator of your local network.
- To get the settings of proxy configured manually, do this:
- Choose your proxy server (for example, FTP Proxy), then enter the number of its port and its address into the corresponding fields you can see at right.
- In case the proxy server has got password protection, tick the checkbox “Proxy server requires a password”. Next, type in your password and the name of your account into the fields Password and Username.
If you’d like to bypass the settings of proxy for some computers on the web (hosts), as well as for some segments on the web (domains), you should add the addresses of such hosts and domains into the corresponding field, called “Bypass proxy settings for these Domains and Hosts.” This may help if you are going to check on receiving some information straight from a domain or a host instead of information that has been cached on your proxy server.
- For bypassing a single domain, you should enter its name (for instance, etsy.com).
- For bypassing all sites of a domain, you should put an asterisk (*) right before the name of the domain (for instance, *etsy.com).
- For bypassing only a domain’s certain part, you should have every part specified (for instance, store.etsy.com).
