Port Forwarding
Rules
Configuring the firewall requires a use of the commands listed in Table 5.
Table 6 - Port Forwarding Configuration
Command Description
wl-route-default
This sets the default port forwarding setting.
forward
All incoming packets on the wireless interface are
forwarded to the address defined by eth-ip.
drop
All incoming packets on the wireless interface are
dropped.
If configured for forward all incoming requests, except
broadcast messages, will be forwarded to the IP address defined by
the eth-ip setting. Relaying of broadcast messages must be
explicitly enabled with the firewall rules for each port used by the
broadcast messages.
If configured for drop no traffic will be forwarded to the
Ethernet interface, essentially creating a firewall to the Ethernet
interface and clients on the interface. In this case adding rules will
allow specific traffic to be forwarded to the Ethernet interface.
The default is forward.
