Chapter 6 Configuration Basics

PREREQUISITES Interfaces, addresses (HOST)

Example: Suppose you have an FTP server with a private IP address connected to a DMZ port. You could configure a NAT rule to forwards FTP sessions from the WAN to the DMZ.

1Click Configuration > Network > NAT to configure the NAT entry. Add an entry.

2Name the entry.

3Select the WAN interface that the FTP traffic is to come in through.

4Specify the public WAN IP address where the ZyWALL will receive the FTP packets.

5In the Mapped IP field, list the IP address of the FTP server. The ZyWALL will forward the packets received for the original IP address.

6In Mapping Type, select Port.

7Enter 21 in both the Original and the Mapped Port fields.

6.5.10 HTTP Redirect

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.

MENU ITEM(S) Configuration > Network > HTTP Redirect

PREREQUISITES Interfaces

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

1Click Configuration > Network > HTTP Redirect.

2Add an entry.

3Name the entry.

4Select the interface from which you want to redirect incoming HTTP requests (lan1).
