5 Configuring Clustering

This chapter describes IPSO’s clustering feature and provides instructions for configuring clusters. It includes information about upgrading from IPSO 3.6 to IPSO 3.7 or later if you have a cluster configured with IPSO 3.6, and it also presents information about how to configure Check Point’s NGX to work with an IPSO cluster.

IP Clustering Description

IPSO lets you create firewall/VPN clusters that provide fault tolerance and dynamic load balancing. A cluster consists of multiple appliances (nodes) that share common IP addresses, and it appears as a single system to the networks connected to it.

A cluster continues to function if a node fails or is taken out of service for maintenance purposes. The connections being handled by the failed node are transferred to one of the remaining nodes.

IPSO clusters are also scalable with regard to VPN performance—as you add nodes to a cluster, the VPN throughput improves.

IPSO clusters support a variety of Check Point NGX features, including:

„Synchronizing state information between firewalls

„Firewall flows

„Network address translation

„VPN encryption

Note

All cluster nodes must run the same versions of IPSO and NGX.

Using Flash-Based Platforms

Do not combine an IP2250 with any other model in an IP cluster. That is, the other platform must also be an IP2250. See “Clustering IP2250 Platforms” for more information about this and other details that are specific to the IP2250.
