As you can see, the communication rules are listed here by their acceptance (
Accept/Deny/Reject)
with the directions of the communication (
br-lan to wan or other).
Here, you can check or modify these firewall rules for the communication, at the
Input
(incoming),
Output
(outgoing) and
Forward
operations one by one by
accept
it, or
reject
,
drop.
You can
Delete
the settings or
modify. Below, at
Zones
part you can
a new rule
to the current ones. You also can
or
an existed rule. Save modified settings
by
Save & Apply
button.
When you’d like to
add new rule to the firewall settings,
it must done
carefully
, because you
can disable or tilt some ports out of the communication so easy (which ports can be used by the
device (by default) or they are necessary to existing for some network services or could required by
some other running tasks). E.g. Port nr. 67 is used by DHCP service and the DNS which is also using
a dedicated port (nr. 53).
