2.3.1. Procedure – IP filtering using a zone
Purpose:
Firewall rules can select the service to be started based on the zone that the server and the client belongs to. Zones are organized based on IP addresses, the rule specifies which clients can use which services to access the specified servers. To create whitelists using a zone, complete the following steps.
Steps:
Create a zone containing only the servers that require client-side authentication (or that have other reasons why the connection cannot be proxied).
Select the site that contains the firewall host, then click , and create a new zone (for example,
banks).Select the newly created zone, and add a network to the zone, that is, specify the and of the target servers. Include only the servers that you want to be available via encrypted but not proxied channels.

Select your firewall host, navigate to , then click .
Create a new service, for example,
intra_PLUG_banks.Select .
