ZyWALL 2 Plus User’s Guide

The following screen displays when the ZyWALL is set to bridge mode. 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. 

IP Assignment 

For the WAN, if the ZyWALL gets its IP address automatically from an ISP, this 

displays DHCP client when you’re using Ethernet encapsulation and IPCP Client 

when you’re using PPPoE or PPTP encapsulation. Static displays if the WAN 

port is using a manually entered static (fixed) IP address.
For the LAN, DHCP server displays when the ZyWALL is set to automatically 

give IP address information to the computers connected to the LAN. DHCP relay 

displays when the ZyWALL is set to forward IP address assignment requests to 

another DHCP server. Static displays if the LAN port is using a manually entered 

static (fixed) IP address. In this case, you must have another DHCP server on 

your LAN, or else the computers must be manually configured. 
For the dial backup port, this shows N/A when dial backup is disabled and IPCP 

client when dial backup is enabled.

Renew

If you are using Ethernet encapsulation and the WAN port is configured to get the 

IP address automatically from the ISP, click Renew to release the WAN port’s 

dynamically assigned IP address and get the IP address afresh. Click Dial to dial 

up the PPTP, PPPoE or dial backup connection. Click Drop to disconnect the 

PPTP, PPPoE or dial backup connection.
