To configure access rules for a policy, select the Policy tab of the Policy Configuration dialog box.
The Connections are drop-down list defines whether traffic that matches the rules in the policy is allowed or denied. To configure how traffic is handled, select one of these settings:
Allowed
The XTM device allows traffic that uses this policy if it matches the rules you set in the policy. You can configure the policy to create a log message when network traffic matches the policy.
Denied
The XTM device denies all traffic that matches the rules in this policy and does not send a notification to the device that sent the traffic. You can configure the policy to create a log message when a computer tries to use this policy. The policy can also automatically add a computer or network to the Blocked Sites list if it tries to start a connection with this policy.
For more information, see Block Sites Temporarily with Policy Settings.
Denied (send reset)
The XTM device denies all traffic that matches the rules in this policy. You can configure it to create a log message when a computer tries to use this policy. The policy can also automatically add a computer or network to the Blocked Sites list if it tries to start a connection with this policy
For more information, see Block Sites Temporarily with Policy Settings.
With this option, the XTM device sends a packet to tell the device which sent the network traffic that the session is refused and the connection is closed. You can set a policy to return other errors instead, which tell the device that the port, protocol, network, or host is unreachable. We recommend that you use these options with caution to ensure that your network operates correctly with other networks.
The Policy tab also includes:
For example, you could configure a ping packet filter to allow ping traffic from all computers on the external network to one web server on your optional network. However, when you open the destination network to connections over the port or ports that the policy controls, you can make the network vulnerable. Make sure you configure your policies carefully to avoid vulnerabilities.
To add members to your access specifications:
The list contains the members you can add to the From or To lists. A member can be an alias, user, group, IP address, or range of IP addresses.
The source and destination can be a host IP address, host range, host name, network address, user name, alias, VPN tunnel, or any combination of those objects.
For more information on the aliases that appear in the From and To list, see About Aliases.
