To utilize the firewall the module must be configured to allow traffic from the
Ethernet interface to the wireless interface based upon IP traffic rules, these
rules include the ability to block or allow access based upon target IP address,
protocol and port. The module supports the use of multiple rules and applies
them based upon the priority in the rule list. Priority of the list is based upon the
order in which the rules were entered, first being highest last being lowest.
Configuring the firewall requires a use of the commands listed in Table 5.
Table 5 - Ethernet Firewall Commands
Command Description
eth-route-default
This sets the default firewall settings.
accept All packets are relayed to the wireless interface.
drop
All packets are dropped and are not relayed to the
wireless interface.
If configured for accept all outgoing requests will be
forwarded, except broadcast messages, essentially turning off the
firewall. 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
wireless interface. In this case adding rules will allow specific traffic to
be forwarded to the wireless interface.
The default is accept.
