13.2 Static routes
However, the router R2 is not able to route frames between a device like L1 belonging to the LAN
network and a device connected to “network 6” (see the drawing hereafter).

In that case, it is necessary to enter the route to that hidden “network 6”; that route is called a static
route.
A static route consists in a table which describes a destination network (IP address and netmask) and
the IP address of the neighbour router through which an IP packet to that destination must pass.
Router 2 static routes :
Active Route name Destination Netmask Gateway
Yes Network 6 192.168.6.0 255.255.255.0 192.168.5.1
Yes Network 1 192.168.1.0 255.255.255.0 192.168.2.1
Yes Network
Remote WAN
192.168.4.0 255.255.255.0 192.168.5.128
Remark :
It is not necessary to enter in the router R2 the static route to the WAN network nor to the remote LAN
network, that routes have been automatically created by the router respectively when the WAN IP
address has been entered and when the VPN has been configured.
To set a static route,
• Select the “Configuration” menu, the “network” menu the “Routing” menu and then “Static
routes”.
• click the “Add a route” button.
“Destination IP address”
& “netmask” parameters :
Enter the destination network IP address and netmask.
“Gateway IP address” parameters
:
Enter the Ip address of the gateway through which the IP packets intended for that network must
pass.
