To-ZyWALL Rules
Rules with
ZyWALL
as the
To Zone
apply to traffic going to the ZyWALL itself. By
default:
• The firewall allows only LAN, WLAN, or WAN computers to access or manage the
ZyWALL.
• The ZyWALL drops most packets from the WAN zone to the ZyWALL itself,
except for VRRP traffic for Device HA and ESP/AH/IKE/NATT/HTTPS services for
VPN tunnels, and generates a log.
• The ZyWALL drops most packets from the DMZ zone to the ZyWALL itself,
except for DNS and NetBIOS traffic, and generates a log.
When you configure a firewall rule for packets destined for the ZyWALL itself,
make sure it does not conflict with your service control rule. See
for more information about service control (remote management). The
ZyWALL checks the firewall rules before the service control rules for traffic
destined for the ZyWALL.
You can configure a To-ZyWALL firewall rule (with
From Any To ZyWALL
direction) for traffic from an interface which is not in a zone.
Global Firewall Rules
Firewall rules with
from any
and/or
to any
as the packet direction are called
global firewall rules. The global firewall rules are the only firewall rules that apply
to an interface or VPN tunnel that is not included in a zone. The
from any
rules
apply to traffic coming from the interface and the
to any
rules apply to traffic
going to the interface.
Firewall Rule Criteria
The ZyWALL checks the schedule, user name (user’s login name on the ZyWALL),
source IP address, destination IP address and IP protocol type of network traffic
against the firewall rules (in the order you list them). When the traffic matches a
rule, the ZyWALL takes the action specified in the rule.
User Specific Firewall Rules
You can specify users or user groups in firewall rules. For example, to allow a
specific user from any computer to access a zone by logging in to the ZyWALL, you
can set up a rule based on the user name only. If you also apply a schedule to the
firewall rule, the user can only access the network at the scheduled time. A user-
aware firewall rule is activated whenever the user logs in to the ZyWALL and will
be disabled after the user logs out of the ZyWALL.
