Distributed Cloud Firewall Field Reference

This table describes the fields to configure when creating a Distributed Cloud Firewall (DCF) rule.

Field Description

Name

Distributed Cloud Firewall rule name.

Source Groups

The SmartGroup(s) that originate traffic. You must create the SmartGroups before creating a DCF rule.

You must include at least one SmartGroup.

Destination Groups

The Destination Group is always Internet.

WebGroups

Select the WebGroups that filter egress traffic. These groups must be created before creating a DCF rule. When you monitor/protect a VPC/VNet, WebGroups are created automatically based on the trusted domains.

Protocol

Select TCP, UDP, ICMP, or Any. If you select TCP or UDP you can enter a port number or port range.

Ports

Select the port that corresponds to the selected protocol.

Action

This determines the action to be taken on the traffic.

  • Permit: Rule is enforced (pushed to gateways); logging is optional

  • Deny: Rule is enforced (pushed to gateways); logging is optional

  • Watch: Rule is not enforced and logging is automatically enabled

Logging

If this slider is On, information related to the action (such as five-tuple, source/destination MAC address, etc.) is logged.

After the rule is created you can enable or disable logging from the vertical ellipsis 20 menu next to the rule.

Aviatrix recommends not logging Permit rules.

Ensure TLS

Turn On this slider if you want any traffic that matches the ports and Source and Destination Groups, but that is not TLS, to be denied. Traffic is also denied (dropped) even if it is HTTP traffic that matches the domains or URLs in the WebGroups.

Place Rule

Select Above, Below, Top, Bottom, or Priority.

Existing Rule

If you select Above or Below (Place Rule), you must select the existing rule that is affected by the position of the new rule.

Rule Priority

If you selected Priority (Place Rule), enter a priority number for the new rule. If an existing rule already has that priority, it is bumped down in the list. Zero (0) is the highest priority number.

You can change the rule priority after the rule is created (using the arrow icon next to that rule in the Rule table).
