Client
RUT9xx can work as a Wi-Fi client (check
6.5 Chapter
of this manual). Client mode is nearly identical to AP, except
for the fact that most for the options are dictated by the wireless access point that the router is connecting to. Changing
them can result in an interrupted connection to an AP.
In addition to standard options you can also click the
Scan
button to rescan the surrounding area and attempt to
connect to a new wireless access point.

A “Drop” action is performed on a packet that is
determined to be invalid
2. Input
Reject/Drop/Accept
DEFAULT* action that is to be performed for
packets that pass through the Input chain.

Reject/Drop/Accept
DEFAULT* action that is to be performed for
packets that pass through the Output chain.
4. Forward
Reject/Drop/Accept
DEFAULT* action that is to be performed for
packets that pass through the Forward chain.
*DEFAULT: When a packet goes through a firewall chain it is matched against all the rules for that specific chain. If
no rule matches said packet, an according Action (either Drop or Reject or Accept) is performed.
Accept – Packet gets to continue down the next chain.
Drop – Packet is stopped and deleted.
Reject – Packet is stopped, deleted and, differently from Drop, an ICMP packet containing a message of rejection
is sent to the
source
of the dropped packet.
