Configure IP Address Ranges

To configure ranges of IP addresses under IPv4 or IPv6 that you consider safe, specify these addresses on Secure Web Gateway.

Use CIDR notation to specify these addresses. For information about this notation, see Configuring IP Addresses Using CIDR notation.

1. On the user interface for Secure Web Gateway, place your mouse pointer over the settings icon in the top right corner, then select Infrastructure > Web Gateway Setup from the drop-down menus.

2. On the setup main page, scroll down to Configure Locations and click New Location.

3. On the Configure Location page, type a name for the location in the Name field, for example, London.
   
   

4. If you want to add SAML authentication as method for authenticating users who send requests for web access, select a configuration from the list provided under Select SAML Configuration. Users are then authenticated according to the settings of this configuration.
   
   If you have configured SAML authentication as part of your web policy, select None here. Otherwise, SAML authentication will not use the settings you have configured for your web policy, but the settings of the configuration that you have selected here.
   
   To use advanced settings for SAML authentication, you need to configure them under your web policy. 

5. If you want to store log data about web traffic in a particular region, select this region from the list provided under Log Data Residency.

6. As mapping type for this location, select IP Range Mapping.
   
   

7. Under IP Range, type the range of IP addresses you want to specify, for example, 100.32.0.0/10. You can also add a plain-text comment on each range. Use the + icon to add more ranges.
   
   

8. Click Save.

You have now configured a range or ranges of IP addresses that you consider safe. When users send web traffic from an address within these ranges, they pass authentication on Secure Web Gateway.
