Default Policies
The Default Policies section sets the basic firewall rules.
Default Policies

Sets the default firewall rules to accept or reject data flow between the following interfaces:
o LAN to WAN
o LAN to LAN
o LAN to LOCAL
o WAN to LOCAL

Sets the action for each rule:
o Accepted: the data is allowed to pass from one interface type to the other interface type.
o Rejected: the data is not allowed to pass form one interface type to the other interface type; the
gateway drops the data packets and sends a reject message to the source of the packets.
o Dropped: the data is not allowed to pass from one interface type to the other interface type; the
gateway drops these data packets without sending a reject message.
NOTE: The WAN to LOCAL traffic is by default "Dropped". This makes sure that no traffic coming from
the Internet can enter the gateway.
