 Chapter 12 Virtual Servers

ZyWALL (ZLD) CLI Reference Guide

The following command creates virtual server WAN-LAN_H323 on the wan1 interface that maps IP 
addresses 10.0.0.8 to 192.168.1.56. for TCP protocol traffic on port 1720. It also adds a NAT 
loopback entry.

The following command shows information about all the virtual servers in the ZyWALL.

ip virtual-server profile_name 

interface interface_name original-ip 

{any | IP | address_object} map-to 

{address_object | ip} map-type 

original-service

 service_object 

mapped-service service_object [nat-

loopback [nat-1-1-map] [deactivate] | 

nat-1-1-map [deactivate] | 

deactivate]

Creates or modifies the specified virtual server and maps the specified 
(destination IP address, protocol, and service object) to 

the specified 

(destination IP address and service object)

. The original destination IP is 

defined by the specified interface (any), the specified IP address (IP), or the 
specified address object (address-object). NAT loopback allows local users 
to use a domain name to access this virtual server.

nat-1-1-map

: means the NAT type is either 1:1 NAT or many 1:1 NAT. See 

 for more information.

Using this command without nat-1-1-map means the NAT type is Virtual 
Server. This makes computers on a private network behind the ZyWALL 
available to a public network outside the ZyWALL (like the Internet). 

The deactivate command disables the virtual server rule.

ip virtual-server {activate | 

deactivate} profile_name

Activates or deactivates the specified virtual server.

ip virtual-server delete profile_name

Deletes the specified virtual server.

ip virtual-server flush

Deletes all virtual servers.

ip virtual-server rename profile_name 

Renames the specified virtual server from the first profile_name to the 
second profile_name.
