Chapter 5 Configuration Basics
8 For the Next Hop fields, select Interface as the Type if you have a single WAN
connection or Trunk if you have multiple WAN connections.
9 Select the interface that you are using for your WAN connection (wan1 and wan2 are the
default WAN interfaces). If you have multiple WAN connections, select the trunk.
10 Specify the amount of bandwidth FTP traffic can use. You may also want to set a low
priority for FTP traffic.
The ZyWALL checks the policy routes in the order that they are listed. So
make sure that your custom policy route comes before any other routes that
would also match the FTP traffic.

5.4.12 Firewall

The firewall controls the travel of traffic between or within zones. You can also configure the
firewall to control traffic for virtual server (port forwarding) and policy routes (NAT). You can
configure firewall rules based on schedules, specific users (or user groups), source or
destination addresses (or address groups) and services (or service groups). Each of these
objects must be configured in a different screen.
To-ZyWALL firewall rules control access to the ZyWALL. Configure to-ZyWALL firewall
rules for remote management. By default, the firewall allows HTTP management access from
the LAN zone and HTTPS management access from any zone. The ZyWALL drops packets
from the WAN or DMZ zone to the ZyWALL itself, except for Device HA and VPN traffic.

Example: Suppose you have a SIP proxy server connected to the DMZ zone for VoIP calls.
You could configure a firewall rule to allow VoIP sessions from the SIP proxy server on DMZ
to LAN1 so VoIP users on LAN1 can receive calls.
1 Create a VoIP service object for UDP port 5060 traffic (Object > Service).
2 Create an address object for the VoIP server (Object > Address).
3 Click Firewall to go to the firewall configuration.
4 Select from the DMZ zone to the LAN1 zone, and add a firewall rule using the items
you have configured.
• You don't need to specify the schedule or the user.
• In the Source field, select the address object of the VoIP server.
