Routes
Click Routes to list all the entries in the system routing table.
airOS examines the destination IP address of each data
packet traveling through the system and chooses the
appropriate interface to forward the packet to. The system
choice depends on static routing rules, the entries that
are registered in the system routing table. Static routes to
specific hosts, networks, or the default gateway are set up
automatically according to the IP configuration of all the
airOS Configuration Interfaces.
Note: Static routes also can be added manually.
For more information, refer to “Static Routes” on
page 26.
Destination Displays the IP address of the destination
network or destination host.
Gateway Displays the IP address of the appropriate
gateway.
Netmask Displays the netmask for the destination
network: 255.255.255.255 for a host destination, and 0.0.0.0
for the default route.
Note: The default route is the route used when no
other routes for the destination are found in the
routing table.
Interface Displays the interface to which packets for a
particular route will be sent.

Firewall
(Available if Firewall is enabled on the Network page.) Click
Firewall to list all the entries in the firewall table.
By default, there are no firewall rules.
If the device is operating in Bridge mode, the table lists
active firewall entries in the FIREWALL chain of the
standard ebtables filter table.
If the device is operating in Router mode, the table
lists active firewall entries in the FIREWALL chain of the
standard iptables filter table.
IP and MAC level access control and packet filtering in
airOS are implemented using an ebtables (bridging) or
iptables (routing) firewall that protects the resources of
a private network from outside threats by preventing
unauthorized access and filtering specified types of
network communication.

Configure firewall rules on the Network page. See
“Firewall” on page 25 (Bridge mode) or “Firewall” on
page 25 (Router mode) for additional details.
Port Forward
(Available if Port Forwarding is enabled in Router mode.)
Click Port Forward to list all port forwarding rules.
Port forwarding allows you to connect to a specific service
such as an FTP server or web server. Port forwarding
creates a transparent tunnel through a firewall/NAT,
granting access from the WAN side to the specific network
service running on the LAN side.
Chain PortForward Displays active port forward entries
in the PREROUTING chain of the standard iptables nat
table, while the device is operating in Router mode.
Refresh To update the information, click Refresh.
Configure port forwarding rules on the Network page. See
“Port Forwarding” on page 26 for additional details.
DHCP Leases
(Available if DHCP is enabled on the Network page.)
Click DHCP Leases to display the current status of the IP
addresses assigned by the device’s DHCP server to its local
clients.
MAC Address Displays the client’s MAC address.
IP Address Displays the client’s IP address.
Remaining Lease Displays the remaining time of the
leased IP address assigned by the DHCP server.
Hostname Displays the device name of the client.
Refresh To update the information, click Refresh.
Configure DHCP on the Network page. See “DHCP” on
page 19 for additional details.
