Deploying a transparent mode firewall doesn’t require any changes of settings on the original network 
topology. It works as bridge/switch; therefore, all the hosts can communicate with each other as without 
firewall in between. At the same time, the transparent firewall can check the packets passing through it 
and block attacks and limit unauthorized access through access control right.   
 
In the following section, we will explain how to configure ZyWALL as bridge firewall. Therefore, all 
hosts and servers can keep using the same IP as that of current network.
