• Src Port The source port of the TCP/UDP packet
(specified within the packet header), usually it is the port
of the host system application which sends the packets.
• Destination IP/mask The destination IP of the packet
(specified within the packet header), usually it is the IP
of the system which the packet is addressed to.
•
Dst Port The destination port of the TCP/UDP packet
(specified within the packet header), usually it is the
port of the host system application which the packet is
addressed to.
•
Comment Field used to enter a brief description of the
firewall entry.
•
On Enables or disables the effect of the particular
firewall entry. All the added firewall entries are saved in
the system configuration file, however only the enabled
firewall entries will be active during AirRouter operation.
•
Not Can be used for inverting the Source IP/mask,
Source Port, Destination IP/mask and Destination Port
filtering criteria (i.e. if not is enabled for the specified
Destination Port value 443, the filtering criteria will be
applied to all the packets sent to any Destination Port
except the 443 which is commonly used by HTTPS).
Firewall entries can be saved by clicking Save or discarded
by clicking Cancel in the Firewall configuration window.
All active firewall entries are stored in the FIREWALL chain
of the iptables filter table, while the device is operating
in Router mode. Please refer to the iptables tutorial for
detailed description of the firewall functionality in Router
mode.
Click Change to save the changes made on the Network
tab.
Static Routes
In this section you can manually add static routing rules to
the System Routing Table, this allows you to specify that a
specific target IP address (es) passes through a determined
gateway. Click Configure to add an entry.
For each entry you must specify a valid Target Network IP,
Netmask, Gateway IP, and optionally a comment. Select
On to enable the rule. Click Save to save your entries or
Cancel to discard them.
Advanced
The Advanced tab handles advanced routing and wireless
settings. The advanced wireless settings should be used
by technically advanced users who have a sufficient
knowledge about wireless LAN technology. These settings
should not be changed unless you know the effect the
changes will have on your AirRouter.
Advanced Wireless Settings
The 802.11n data rates include MCS0, MCS1, MCS2, MCS3,
MCS4, MCS5, MCS6, MCS7 for 1x1 chain devices and MCS8,
MCS9, MCS10, MCS11, MCS12, MCS13, MCS, MCS15 for
2x2 chains devices. The ACK timeout has a critical impact
on performance in 802.11n outdoor links.
RTS Threshold Determines the packet size of a
transmission and, through the use of an access point,
helps control traffic flow. The range is 0-2346 bytes, or
word “off”. The default value is 2346 which means that RTS
is disabled.
RTS/CTS (Request to Send/Clear to Send) are the
mechanisms used by the 802.11 wireless networking
protocol to reduce frame collisions introduced by the
hidden terminal problem. RTS/CTS packet size threshold is
0-2346 bytes. If the packet size the node wants to transmit
is larger than the threshold, the RTS/CTS handshake
gets triggered. If the packet size is equal to or less than
threshold the data frame gets sent immediately.
