Configuring Firewall Load Balancing in the P333R-LB
The following figure illustrates a simple transparent routing FWLB configuration.

Transparent Routing FWLB Sample Configuration
Note:
1. When configuring routing firewalls as Real Servers, you must give an ID to each
Real Server. This ID must match the ID given to the same firewall on the second
load balancer.
2. The P333R-LB performs load balancing on traffic that arrives to its routing
interfaces. Therefore, IP routes in the network must be configured to pass through
the P333R-LB.

To configure your network as in Figure 14.1, the following should be done:
•
•
The LAN routers (or hosts) should be configured with 10.4.1.3 as the next hop
toward the WAN (the default gateway in many cases).

The firewalls must be configured to allow ICMP Echo to pass between the two
load balancers (10.1.1.3 and 10.2.1.3) for health-check purposes.
