Chapter 1. Firewall Rules for Red Hat OpenStack Platform
This article provides a link to the Red Hat OpenStack network flow matrix. The matrix describes network flows created by the director on Red Hat OpenStack Platform. These ports are required for services running on the overcloud. Use this information to determine firewall rules.
1.1. Red Hat OpenStack Network Flow Matrix
The network flow matrix is a comma separated values (CSV) file that describes flows to and from OpenStack services.
NOTE: The network flow matrix describes common traffic flows. It does not describe every possible flow. Some flows that are not described in this matrix might be critical to operation. For instance, if you block all traffic and then selectively open only the flows described here, you might unintentionally block a necessary flow. That could cause issues that are difficult to troubleshoot.
The matrix describes flows in the following columns.
- Service
- The OpenStack service.
- Protocol
- Transmission protocol.
- Dest. Port
- Destination port.
- Source Object
- Source of data.
- Dest. Object
- Destination of data.
- Source/Dest Pairs
- Valid source and destination pairs.
- Dest. Network
- Destination network.
- ServiceNetMap Parent
- Determines the network type used for each service.
- Traffic Description
- Notes about the traffic flow.
