Routes
Lists 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.
Destination Displays the IP address of the destination
device.
Gateway Displays the IP address of the appropriate
gateway.
Netmask Displays the netmask of the destination device.
Interface Displays the interface that the destination
device is on.

Firewall
When the firewall is enabled on the Network tab, this
option is available. 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 or SOHO Router mode,
the table lists active firewall entries in the FIREWALL chain
of the standard iptables filter table.
Firewall Rules 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.

transparent tunnel through a firewall/NAT, granting access
from the WAN side to the specific network service running
on the LAN side.
Port Forward Rules Lists active port forward entries in
the PREROUTING chain of the standard iptables nat table,
while the device is operating in Router or SOHO Router
mode.
