Click Configuration > Network > NAT to configure the NAT entry. Add an entry.

Name the entry.

Select the WAN interface that the FTP traffic is to come in through.

Specify the public WAN IP address where the ZyWALL will receive the FTP packets.

In the Mapped IP field, list the IP address of the FTP server. The ZyWALL will 
forward the packets received for the original IP address.

In Mapping Type, select Port.

Enter 21 in both the Original and the Mapped Port fields.

Configure this feature to have the ZyWALL transparently forward HTTP (web) 
traffic to a proxy server. This can speed up web browsing because the proxy server 
keeps copies of the web pages that have been accessed so they are readily 
available the next time one of your users needs to access that page.

The ZyWALL does not check to-ZyWALL firewall rules for packets that are 
redirected by HTTP redirect. It does check regular (through-ZyWALL) firewall 
rules.

Example: Suppose you want HTTP requests from your LAN to go to a HTTP proxy 
server at IP address 192.168.3.80. 

Click Configuration > Network > HTTP Redirect. 

Add an entry.

Name the entry.

Select the interface from which you want to redirect incoming HTTP requests ().

Specify the IP address of the HTTP proxy server.

Specify the port number to use for the HTTP traffic that you forward to the proxy 
server.
