Enabling communications for network services instead of adding a rule

You can enable the options that automatically allow communication between certain network services so you do not have to define the rules that explicitly allow those services. You can also enable traffic settings to detect and block the traffic that communicates through NetBIOS and token rings.
You can allow outbound requests and inbound replies for the network connections that are configured to use DHCP, DNS, and WINS traffic.
The filters allow DHCP, DNS, or WINS clients to receive an IP address from a server. It also protects the clients against attacks from the network with the following conditions:
If the client sends a request to the server
The client waits for five seconds to allow an inbound response.
If the client does not send a request to the server
Each filter does not allow the packet.
When you enable these options,
Symantec Endpoint Protection
permits the packet if a request was made; it does not block packets. You must create a firewall rule to block packets.
To configure these settings in mixed control, you must also enable these settings in the
Client User Interface Mixed Control Settings
dialog box.
