You can connect any site where you run a local network to Secure Web Gateway to route web traffic from your site to it. For any connection, you can configure a range of IP addresses that you consider safe or a tunnel to route the traffic through it.
For this configuration, you configure one or more sites as a location. To set up a tunnel from a location to Secure Web Gateway, you configure settings for a networking device or SD-WAN service that you run in your network. The traffic is then routed from the device or service to Secure Web Gateway and authenticated.
The routing follows the IPsec or GRE tunneling protocol.
Depending on the solution you have chosen, you need to complete one of the following configuration tasks:
Configure IP address ranges — When users send web traffic from IP addresses within these ranges, they pass authentication on Secure Web Gateway. For more information, see About Configuring IP Address Ranges.
- Configure an IPsec tunnel — When web traffic is routed through this type of tunnel, it follows the IPsec protocol. For more information, see About Configuring IPsec Tunnels.
Configure GRE tunnels — When web traffic is routed through this type of tunnel, it follows the GRE protocol. For more information, see About Configuring GRE tunnels.
