Additional NSP component firewall and NAT rules

Overview

Firewall rules are applied to the incoming network interface traffic. As a rule, firewall rules are not applied to the outgoing network interface traffic.

For installations using RHEL as the Operating System, the RHEL supplied firewall can be used to filter network traffic using filter rules lists. Only experienced system administrators with extensive knowledge of the RHEL firewall should attempt to implement the filter rules lists provided with each component. All others should disable the RHEL firewall.

The installation of each component will include the filter rules lists to be applied for successful communication between different NSP components, XML API clients, and network elements. The table below defines the location

It is imperative that all rules are considered completely for the NSP systems to inter-operate correctly. The following tables will define the connection details. Within the section there will be a number of conditions that indicate whether or not that particular table or connection needs to be applied.

See NFM-P Network Address Translation for supported NAT configurations.

NFM-P server firewall and NAT rules

When there is a firewall at the NSP auxiliary database, the following initiating connection details must be considered. Network Interface number is in reference to Figure 7-3, Distributed NFM-P server/database deployment with multiple network interfaces.

Since the inter-node communication should traverse a private LAN, it is not recommended to implement a firewall on this interface.
