What Does Bypass Proxy Settings Mean
How to Use the Bypass Proxy Server for Local Addresses
i Creatas/Creatas/Getty Images The Bypass Proxy Server for Local Addresses option in Windows 8’s Internet Options dialog enables you to circumvent an active proxy when accessing local resources. In general, Windows recognizes addresses like “intranet” as a local address and bypasses the proxy. However, if you add periods or use an IP address, such as ” or ” Windows fails to recognize the address as local. Therefore, if you need to bypass these local addresses, add manual exceptions for them. Step 1Type “Internet Options” while viewing the Windows 8 Start screen, click “Settings” and select “Internet Options. ” Step 2Click the “Connections” tab and select “LAN Settings. ” Step 3Check “Bypass Proxy Server for Local Addresses. ” If this option is grayed out, you don’t have “Use a Proxy Server for Your LAN” checked, which means you’re not using a proxy server through Windows for any address. Step 4Click “Advanced” and enter each local address in the Exceptions box. Separate each address with a semicolon. Step 5Click “OK” in all three opened windows to accept your changes. References Tips Internet Explorer and Chrome both rely on the Internet Options settings for proxy information, so you don’t need to configure them separately. Firefox optionally uses its own proxy settings, so you might need to add exceptions in Firefox. Click “Firefox | Options | Options | Advanced | Network | Settings” and enter exceptions in the No Proxies For box, separated by commas. This option is only available when using the “Manual Proxy Configuration” option. Writer Bio C.

Adding and importing sites that bypass the proxy – Forcepoint
The Proxy Bypass tab of the Bypass Settings page enables you to define sites that bypass the cloud service for all policies. This may include, for example, internal sites that are not accessible from the Internet, so the cloud service cannot serve or analyze them.
Note
The URLs included in the bypass list for Office 365 are those domains that are owned by Microsoft and used directly by the Office 365 application, listed here:
This list also includes third-party URLs that host Certificate Revocation Lists (CRLs), which are not included in the bypass when you select the Office 365 checkbox. Bypassing these domains may not be appropriate for all customers.
If you have difficulty installing or using Office 365 with this option selected, you may need to add one or more of these additional URLs as non-proxied domains. If you need further assistance, please contact Technical Support.

Click Import Destinations.
You can add a total of 1000 proxy bypass destinations per policy. Account-level bypass destinations (added via Web > Proxy Bypass) count towards this limit for each policy. For example, if your policy has 10 bypass destinations, and you have 10 account-level bypass destinations, this is counted as a total of 20 destinations for the policy.

Bypass proxy servers for web requests
Some network requests have to bypass the proxy. The most common reason is for local (intranet) addresses. Generally, these addresses don’t contain periods.
To bypass the proxy, select the Bypass proxy server for local (intranet) addresses check box in the Local Area Network (LAN) Settings dialog box. This method bypasses the proxy for all addresses that don’t contain a period (for example, compserv). These addresses will also be resolved directly.
To bypass more complex addresses, set up exceptions for specific addresses or wildcards by using either of the following procedures.
Use the browser settings
If you’re configuring proxy settings on a user’s computer after the deployment, follow these steps:
In Internet Explorer, open the Tools menu, and then select Internet Options.
On the Connections tab, select LAN Settings.
In the Local Area Network Settings dialog box, select the Use a proxy server for your LAN settings check box.
Select the Advanced tab, and enter the appropriate exceptions in the Do not use proxy server for addresses beginning with: box.
Note
Multiple exceptions should be separated by semicolons (“;”).
For more information, see Internet Explorer uses Proxy Server for Local IP address even if the “Bypass Proxy Server for Local Addresses” option is turned on.
Use the Proxy setting in the Internet Explorer Customization Wizard
For more information about this method, see Use the Proxy Settings page in the IEAK 11 Wizard.
Use Group Policy
In earlier versions of the Windows operating system, Internet Explorer Maintenance (IEM) is used to configure Internet Explorer settings by using Group Policy. In Windows 8, the IEM settings have been deprecated in favor of Group Policy Preferences, Administrative Templates (), and the Internet Explorer Administration Kit 10 (IEAK 10).
To configure the proxy setting through a group policy, see How to configure Proxy Settings for Internet Explorer 10 and Internet Explorer 11 as IEM is not available.
More information
A proxy bypass entry may begin by using an,, ftp, or gopher protocol type.
If a protocol type is used, the exception entry applies only to requests for that protocol.
The protocol value is case insensitive. Multiple entries should be separated by semicolons.
If no protocol is specified, any request that uses the address will be bypassed.
If a protocol is specified, requests that use the address will be bypassed only if they are of the indicated protocol type. Address entries are case insensitive, the same as they are for the protocol type.
If a port number is given, the request is processed only if all previous requirements are met and the request uses the specified port number.
To bypass servers, use an asterisk (“*”) as a wildcard to replace actual characters in the exceptions area of the Proxy Settings dialog box.
Enter a wildcard at the beginning of an Internet address, IP address, or domain name that has a common ending. For example, use *. to bypass any entries that end in., such as and
Enter a wildcard in the middle of an Internet address, IP address, or domain name that has a common beginning and ending. For example, the entry * matches any entry that starts as www and ends as com.
Enter a wildcard at the end of an Internet address, IP address, or domain name that has a common beginning. For example, use to bypass any entries that begin as ，such as,, and
To bypass addresses that have similar patterns, use multiple wildcards. For example, use 123. 1*. 66. * to bypass addresses such as 123. 144. 12, 123. 133. 15, and 123. 187. 13.
Use wildcards carefully. For example, the entry * causes Internet Explorer to bypass the proxy for most websites.
If you bypass the proxy for a local domain, use * This method doesn’t use the proxy for any computer name that ends in You can use the wildcard for any part of the name. For more information, see The Intranet Zone.
Proxy Auto Configuration (PAC)
Example of a simple PAC file
The following is a simple PAC file:
function FindProxyForURL(url, host)
{
return “PROXY proxyserver:portnumber”;}
This PAC always returns the proxy proxyserver:portnumber. For more information about how to write a PAC file and the different functions of a PAC file, see Introduction of FindProxyForURL.
