FIGURE 3-4. Problem: The appliance and clients deployed in different
network segments, with router as default gateway of the
appliance and no static routes set
A routing problem occurs whenever the router performs the following:
• Sending SYN/ACK packet back to clients
• Forwarding data to clients
These transactions lead to a decrease in the network throughput.

Problem: Without knowing the
static IP routes, the appliance does
not know where to forward traffic.
Therefore, the appliance forwards
