LAN WAN Inbound Rules and DMZ WAN Inbound Rules
The LAN WAN Rules screen and the DMZ WAN Rules screen list all existing rules for
inbound traffic (from WAN to LAN and from WAN to the DMZ). Any inbound rule that you
create allows additional incoming traffic and therefore increases the traffic load on the WAN
side.
On the LAN WAN screen, if you did not define any rules, only the default rule is listed. The
default LAN WAN inbound rule blocks all access from outside except responses to requests
from the LAN side.
WARNING:
Incorrect configuration of inbound firewall rules can cause serious
connection problems.
Each rule lets you specify the desired action for the connections covered by the rule:
• BLOCK always
• BLOCK by schedule, otherwise allow
• ALLOW always
• ALLOW by schedule, otherwise block
The following sections summarize the various criteria that you can apply to inbound rules and
that might increase traffic.
• For more information about inbound rules, see
• For detailed procedures about how to configure inbound rules, see
Rules
on page 134 and
When you define inbound firewall rules, you can further refine their application according to
the following criteria:
• Services. You can specify the services or applications to be covered by an inbound rule.
If the desired service or application does not display in the list, you must define it using
the Services screen. For more information, see
Customized Services
• WAN destination IP address. You can specify the destination IP address for incoming
traffic. Traffic is directed to the specified address only when the destination IP address of
the incoming packet matches the IP address of the selected WAN interface.
• LAN users (or DMZ users). Only when the IPv4 routing mode is Classical Routing, you
can specify which computers on your network are affected by an inbound rule. When
Classical Routing is enabled, several options are available:
- Any. The rule applies to all computers and devices on your LAN.
- Single address. The rule applies to the address of a particular computer.
- Address range. The rule applies to a range of addresses.
