ZyWALL USG Support Notes

address object you defined, it means turn on the NAT feature and it will refer to the

next-hop setting to execute routing.

For the specific traffic needs to be re-directed to a certain internal server, the virtual

server needs to be configured. This feature allows ports/host mapping from a WAN

interface IP to an internal DMZ/LAN IP. For example, if you want to forward HTTP

traffic with 8080 port to the ZyWALL5 in ZyWALL USG‟s DMZ zone, you need to

configure virtual server to forward <Original IP(ex. WAN1‟s IP):8080> to <Internal

server IP:8080>.

F04. After I installed a HTTP proxy server and set a http

redirect rule, I still can’t access web. Why?

Your proxy server must support a transparent proxy. If your proxy does have this

feature, turn it on. For example, for Squid, you have to have the option

httpd_accel_uses_host_header enabled.

F05. How to limit some application (for example, FTP)

bandwidth usage?

In order to restrict the bandwidth usage for a specific application, you need to employ

AppPatrol feature.

The following steps allow the user to limit the bandwidth usage from of FTP

application:

1. Pick up the FTP application that you want to restrict bandwidth usage and click

“Edit” in AppPatrol > Common page.

2. Click the “Edit” button for default policy, and the “Configuration” page appears.

3. On the “Configuration” page, enter the bandwidth amount you want to limit

bandwidth usage in direction “Inbound” or “Outbound”.

4. Back to “General” page under AppPatrol and check the “Enable BWM” checkbox

then click the “Apply” button to complete the entire configuration.

Note. On the ZLD 1.0 the default setting of bandwidth management is ON and you

cannot change the setting, but on the ZLD 2.0 the default setting of bandwidth

management is off, therefore if you are upgraded from 1.0 to 2.0, the “Enable BWM”

checkbox will be checked.
