Figure 135 Statistics

balancing function has taken effect.
Firewall load balancing configuration example
Network requirements
As shown in Figure 136, two firewalls Firewall A and Firewall B each are connected to internal network
and Internet through an LB device to balance load between the two networks to enhance network
performance.
Firewall load balancing is adopted. LB device A operates as the level 1 LB device, and LB device B the
level 2 LB device.
