IP Routing
9.1 Basic routing function
Once an iP address has been assigned to the R2 router on the LAN interface and another one on the WAN
interface (see drawing hereafter), the ETIC router is ready to route frames …
… between devices connected to the remote LAN network like RL1, and devices connected to the LAN
network like L1 through a VPN;
… between devices connected to the WAN network like W1, and devices connected to the LAN network
like L1
Remark 1 : Firewall rules must be set to authorize WAN to LAN transfer.
Remark 2 : A default gateway address must be entered in each device of the different networks.
9.2 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.
