VPN but not want to route unencrypted traffic through the cluster. For this purpose, you can use a configuration similar to the one shown in the following diagram:

The purpose of this configuration would be to route the outgoing unencrypted traffic through the default gateway and route the outgoing encrypted traffic through the cluster. Traffic that passes through the cluster is NATed so that the source address of a packet is translated to one of the addresses in the IP pool of the cluster node that handles the connection.

How you configure IP pools depends on whether a non-Check Point gateway participates in the VPN:

„If the other end of the tunnel is also a Check Point gateway, you do not need to configure the IP pools in IPSO. Simply follow the instructions in “Using IP Pools When Only Check Point Gateways Are Involved.”

„If the other end of the tunnel is not a Check Point gateway, you must follow the instructions in “Using IP Pools When Only Check Point Gateways Are Involved” and also configure the IP pools in IPSO, as explained in “Configuring IP pools in Cluster Voyager.”

Using IP Pools When Only Check Point Gateways Are Involved

To set up the configuration shown in the previous diagram, you would:

„Configure the IP pools in NGX.

„On the internal router:

„create a default route to the Internet with 192.168.1.1 (the default gateway) as the gateway address.

„create static routes to the IP pool networks with the internal cluster IP address (192.168.1.10) as the gateway address. Do not use the real IP addresses of the internal
