Devices on LAN B and LAN C that needs to send messages back to LAN A will need to have their gateway
addresses directed to the WI-MOD-xxx-E-5W on their respected networks. For example, a LAN B device needs to
send data back to LAN A. The gateway address will need to be configured as 169.254.109.40 as this is the IP
address of the wired side of the LAN B WI-MOD-xxx-E-5W . Any message coming in with a 192.168.0.X IP address
will be directed across the wireless interface to LAN A.
To access the IP Routing Rules configuration page, click IP Routing from the menu. Up to 30 routing rules may be
added to each WI-MOD-xxx-E-5W . The table below summarizes the configurable parameters of a routing rule.
Figure 53 IP Routing
Name
A name that describes the routing rule (max 32 characters).
Destination
The destination network (or host) IP address. To specify a network address, set
the host address to 0. For example, an IP address 192.168.0.0 with netmask
255.255.255.0 specifies a destination network, while 192.168.0.16 specifies a
destination host.
Netmask
The subnet mask for the destination network.
Gateway
The IP address of the next-hop router for the specified destination.
Enabled
Select this checkbox to enable the rule. You can deselect the checkbox to disable a
routing rule without needing to re-enter the information at a later time.
Save Changes
Save changes to non-volatile memory. The module will need to be restarted before
the changes take effect.
Save Changes and
Reset
Save settings to non-volatile memory, and reboot the WI-MOD-xxx-E-5W
module. Once the module has completed the reboot sequence, all changes are
in effect.
NOTE Dedicated Ethernet routes can also be added to the wired Ethernet LAN in place of generating or
adding routing rules in the modems.
4.10 Filtering
The WI-MOD-xxx-E-5W has a filtering feature to reduce unnecessary wireless transmissions and enhance security.
To configure filters, click Filtering on the menu to display the page shown in Figure 54. Filtering applies only to
messages appearing at the wired Ethernet port of the configured WI-MOD-xxx-E-5W module. You can configure
three types of filters
— MAC Addresses, IP Address/Protocol/Port, and ARP. Each filter list may be set as either a
blacklist (to block traffic for listed devices and protocols), or as a whitelist (to allow traffic for listed devices and
protocols).
The filters operate on the following rules:
•
The MAC Address filter is always checked before the IP Address filter.
•
If a message matches a MAC Address filter entry, it is not subsequently processed by the IP Address
