How to set up your FortiWAN Configuring Network Interface (Network Setting)
FortiWAN are designed to work together, which the SLAAC responses router advertisement (including default gateway
and DNS server) to a host and DHCPv6 responses the host an appropriate IPv6 address.
For the details about DHCP, DHCP Relay, SLAAC and DHCPv6, see "Automatic addressing within a basic subnet".
Static Routing Subnet
[Static Routing Subnet] is useful when in LAN a router .is used to cut out a separate subnet which does not connect to
FortiWAN directly. The topology is similar to [Static Routing Subnet: Subnet in DMZ] mentioned previously, and the
only difference is this example is set in LAN rather than in DMZ. In this topology below, a subnet 192.168.99.x is
located in the LAN and connects to router 192.168.34.50, while another subnet 192.168.34.x is located on the LAN
port as well, but connects to FortiWAN directly. The configurations here indicate how FortiWAN to route packets to
subnet 192.168.99.x.
RIP
FortiWAN supports the Routing Information Protocol (RIP v1, v2), RIP employs hot count as the metric, and uses timer
broadcast to update the router. As RIP features configuration simplicity and operation convenience, it has been widely
used across all fields. RIP version 1 (v1)1 was designed to suit the dynamic routing needs of LAN technology-based IP
internetworks, and to address some problems associated with RIP v1, a refined RIP, RIP version 2 (v2) was defined.
RIP v2 supports sending RIP announcements to the IP multicast address and supports the use of authentication
mechanisms to verify the origin of incoming RIP announcements.
Check the field in [RIP] if you have enabled RIP on your private subnet router. Check the field in [RIP v1] if you have
enabled RIP v1 on your private subnet router behind FortiWAN. Thus, FortiWAN can forward packets from the RIP v1-
enabled private subnet. Otherwise, check the field in [RIP v2] if you have enabled RIP v2 on your private subnet router.
