In bridge mode, the ZyWALL functions as a transparent firewall (also known as a bridge
firewall). The ZyWALL bridges traffic traveling between the ZyWALL's interfaces and still
filters and inspects packets. You do not need to change the configuration of your existing
network.
In bridge mode, the ZyWALL cannot get an IP address from a DHCP server. The LAN, WAN,
DMZ and WLAN interfaces all have the same (static) IP address and subnet mask. You can
configure the ZyWALL's IP address in order to access the ZyWALL for management. If you
connect your computer directly to the ZyWALL, you also need to assign your computer a
static IP address in the same subnet as the ZyWALL's IP address in order to access the
ZyWALL.
You can use the firewall and VPN in bridge mode. See the user’s guide for a list of other
features that are available in bridge mode.
