Backup Routes
Using the configuration form on the
Backup Routes
page can be set backing up primary
connection by other connections to internet/mobile network. For each back up connection can
be defined a priority. Own switching is done based on set priorities and state of the connection
(for
Primary LAN
).
If
Enable backup routes switching
option is checked, the default route is selected accord-
ing to the settings below. Namely according to status of enabling each of backup route (i.e.
Enable backup routes switching for Mobile WAN
,
Enable backup routes switching for Primary
LAN
, according to explicitly set priorities and according to status of connection check (if it is
enabled). In addition, network interfaces belonging to individual backup routes have checked
a flag RUNNING. This check fixes for example disconnecting of an ethernet cable.
If
Enable backup routes switching
option is not checked, Backup routes system operates
in the so-called backward compatibility mode. The default route is selected based on implicit
priorities according to the status of enabling settings for each of network interface, as the case
may be enabling services that set these network interfaces. Names of backup routes and
corresponding network interfaces in order of implicit priorities:
•
Mobile WAN (pppX, usbX)
•
Primary LAN (eth0)

Firewall configuration
The first security element which incoming packets must pass is check of enabled source IP
addresses and destination ports. It can be specified IP addresses from which you can remotely
access the router and the internal network connected behind a router. If the
Enable filtering of
incoming packets
item is checked (located at the beginning of the configuration form
Firewall
),
this element is enabled and accessibility is checked against the table with IP addresses. This
means that access is permitted only addresses specified in the table. It is possible to define
up to eight remote accesses. There are the following parameters:
