3. Seamless Incorporation

With its robust networking functionalities, ZyWALL 1050 is easy to integrate into

existing network infrastructure. You can easily implement the following applications. They are

“Transparent firewall”, “Transparent IDP” and “Network Partitioning using VLAN”.

3.1 Transparent Firewall

With transparent firewall, you do not need to change the IP addressing scheme of your

existing network topology. What you need to do is to insert ZyWALL 1050 into your existing

network environment. Bridge the ports you think that need to be included in this bridge

interface. Apply the security policies that you want. And that will be it. Moreover, ZyWALL

1050 supports working as bridge mode and router mode at the same time; which means that

they can co-exist.

3.1.1 Bridge mode & Router (NAT) mode co-exist

Here is an example:

DMZ and WAN zone can be bridged so that servers in the DMZ zone can keep using the same

public IP address (as those in WAN zone) for effortless IP management. IP addressing in LAN

zone is private IP segments. Thus, we need NAT, which is the router mode here. In our

example, ge1 acts as LAN, ge2 and ge3 stands for WAN, ge4 and ge5 stands for DMZ.
