Inbound (WAN to LAN/DMZ) rules restrict access to trac entering your network, selectively allowing only
specic outside users to access specic local resources. By default all access from the insecure WAN side are
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 an inbound rewall rule for each service.
If you want to allow incoming trac, 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 congured;
for this router 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 trac leaving your network, selectively allowing only
specic local users to access specic outside resources. The default outbound rule is to allow access from
the secure zone (LAN) to either the public DMZ or insecure WAN. On other hand the default outbound rule
is to deny access from DMZ to insecure WAN. You can change this default behavior in the Firewall Settings >
Default Outbound Policy page. When the default outbound policy is allow always, you can to block hosts on
the LAN from accessing internet services by creating an outbound rewall rule for each service.
To create a new rewall rule:
