Inbound (WAN to LAN/DMZ) rules restrict access to traffic entering your network,
selectively allowing only specific outside users to access specific local resources.
By default, all access from the insecure WAN is blocked from accessing the
secure LAN, except in response to requests from the LAN or DMZ. To allow
outside devices to access services on the secure LAN, you must create a firewall
rule for each service.
If you want to allow incoming traffic, you must make the router's WAN port IP
address known to the public. This is called “exposing your host.” How you make
your address known depends on how the WAN ports are configured for the
device. You may use the IP address if a static address is assigned to the WAN
port, or if your WAN address is dynamic, a DDNS (Dynamic DNS) name can be
used.
Outbound (LAN/DMZ to WAN) rules restrict access to traffic leaving your network,
by selectively allowing only specific local users to access specific outside
resources. The default outbound rule is to allow access from the secure zone
(LAN) to either the public DMZ or insecure WAN. To block hosts on the secure LAN
from accessing services on the outside (insecure WAN), you must create a firewall
rule for each service.
