Allowed domains

Use the Allowed Domains View to specify the domains and production DNS server that isolated hosts use to gain access to network locations. For example, if hosts are in isolation because they do not have the latest virus definitions for their virus software, they would need to be able to access the web site for their virus software to download virus definitions.

If you have used a valid SSL certificate to secure the portal, add the domain of the CA to the Domains list, such as verisign.com. This allows the host's browser to validate the certificate.

Field

Definition

IP address

The IP address(es) of the production DNS server(s).

If the Prevent the DNS server from making iterative queries check box is enabled, FortiNAC would no longer perform iterative queries to external authoritative servers. If the DNS server does not find the domain, the DNS server will not continue to perform queries to authoritative name servers. The only DNS requests the FortiNAC server will make on behalf of endpoints are to the specified DNS forwarding IPs.

Proxy Auto Config

Optional. If you use a Proxy server, this populates the wpad.dat file with the information that allows a host to learn about the Proxy server. This also adds the Domains listed to allow hosts in Isolation to reach sites related to Anti-Virus or operating system updates required.

See Web proxy for additional information.

Domains

A list of authorized domains that an isolated host is permitted to access, such as microsoft.com.
