ZyWALL 2 Plus User’s Guide

Find firmware at www.zyxel.com in a file that (usually) uses the system model name with a 
.bin extension, for example, "zywall.bin". The upload process uses HTTP (Hypertext Transfer 
Protocol) and may take up to two minutes. After a successful upload, the system will reboot.  
See

 

 for upgrading firmware using FTP/TFTP commands.

Click MAINTENANCE > F/W UPLOAD. Follow the instructions in this screen to upload 
firmware to your ZyWALL.

DHCP

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows 

individual clients (computers) to obtain TCP/IP configuration at startup from a 

server. Unless you are instructed by your ISP, leave the DHCP check box 

selected. Clear it to stop the ZyWALL from acting as a DHCP server. When 

configured as a server, the ZyWALL provides TCP/IP configuration for the 

clients. If not, DHCP service is disabled and you must have another DHCP 

server on your LAN, or else the computers must be manually configured. When 

set as a server, fill in the rest of the DHCP setup fields.
