Preview of Access Rule
The Action, Source, Destination, and Service columns show the ACL entries in
the access rule associated with the policy. These columns are empty if no ACL is
configured for this policy.
Add Exception Policy
Create a new exception policy in this window.
To create a new exception policy, enter a name for the policy, and either specify
an access rule that defines the IP addresses that hosts in the exception list can
access, or enter a redirect URL. The redirect URL should contain remediation
information that enables users to update their virus definition files. You must
provide either an access rule name or a redirect URL. You can specify both.
Name Field
Enter the name for the policy in this field. Do not use question mark (?) characters
or space characters in policy names. Limit each policy name to no more than 256
characters.
Access Rule Field
Enter the name of the access rule that you want to use, or click the button to the
right of this field to browse for an access rule or create a new access rule. The
access rule must contain permit entries that specify the IP addresses that hosts on
the exception list can connect to. The access rule must be a named ACL;
numbered ACLs are not supported.
Redirect URL Field
Enter a URL that contains the remediation information for your network. This
information might contain instructions for downloading virus definition files.
A remediation URL might look like the following:
http://172.23.44.9/update
