Chapter 13: Firewall Load Balancing n 325

15. Add the filters to the ingress ports for the outbound packets.
Redirection filters are needed on all the ingress ports on the clean-side Web switch. Ingress
ports are any that attach to real servers or internal clients on the clean-side of the network. In
this case, two real servers are attached to the clean-side Web switch on port 4 and port 5.
16. Define static routes to the dirty-side IP interfaces, using the firewalls as gateways.
One static route is required for each firewall path being load balanced. In this case, two paths
are required: one that leads to dirty-side IF 2 (10.1.1.1) through the first firewall (10.1.3.10) as
its gateway, and one that leads to dirty-side IF 3 (10.1.2.1) through the second firewall
(10.1.4.10) as its gateway.
N OTE – Configuring static routes for FWLB does not require IP forwarding to be turned on.
17. Apply and save the configuration changes.
