Chapter 13: Firewall Load Balancing

Configure the Clean-Side Web Switch
1.
Define the clean-side IP interfaces.
Create one clean-side IP interface on a different subnet for each firewall being load balanced.

OTE
–
An extra IP interface (IF 1) prevents server-to-server traffic from being redirected.
2.
Configure the dirty-side IP interfaces as if they were real servers on the clean side.
You should already have configured a dirty-side IP interface on a different subnet for each fire-
wall path being load balanced. Create two real servers on the clean-side switch, using the IP
address of each dirty-side IP interface.

OTE
–
Each of the four IP interfaces (two on each Web switch) in this example must be con-
figured for a different IP subnet.
3.
Place the real servers into a real server group.
