Note: If domain name is used in the hostname parameter, DNS Server must be set in the Web UI [System]-> [Network Settings]->[DNS Server] (See “Set DNS server for FortiWAN”).

For more on ICMP related error messages please refer to other ICMP/PING materials.

reactivate: Reactivate the FortiWAN apparatus

reactivate

Reactivating the FortiWAN apparatus will:

  • Reset all system configurations to factory default (See “Appendix A: Default Values” for the details) l Return the system to base-bandwidth (See “License Control” in “Administration”) l Reset Reports database to factory default. All the report data will be deleted.

Using this command will result in all system data being deleted as well as all bandwidth licenses. Before you attempt a reactivation, please make sure the following are complete:.

  • Backup any configuration data (See “Configuration File” in “Administration”). l Backup Reports database (See “Reports Database Tool”).
  • Locate your Bandwidth Upgrade Key if your system is not at base bandwidth, so that the bandwidth license the system had before can be activated by reentering the key.

Note that if your system is not at base bandwidth and you do not have your Bandwidth Upgrade Keys, please contact Fortinet CSS before attempting a reactivation.

reboot: Restart FortiWAN

reboot [-t <second>]

Restart FortiWAN immediately or restart it after a time period.

-t: Reboot FortiWAN after seconds. Parameter second is for this.

<second>: The parameter in specifying the time period (in second) system waits for to reboot.

Example: reboot -t 5 to restart the system after 5 seconds.

resetconfig: Reset system configurations to factory defaults

resetconfig

resetconfig <ip_address/netmask<@port>>

resetconfig <ip_address/netmask<@port>> <network_ip/netmask@gateway_ip>

Reset system configurations to factory default. This will delete all system settings including accounts of Web UI, network settings and all the other system settings and service settings (See “Appendix A: Default Values” for the details). Please backup all the configurations (See “Configuration File” in “Administration”) before executing this command. This command makes no changes to Reports database and bandwidth license, as opposed to command reactivate.

Since command resetconfig will return IP address of LAN and WAN ports to the default values such as 192.168.0.1/255.255.255.0, 192.168.1.1/255.255.255.0 and 192.168.2.1/255.255.255.0, users might need to change the IP address of their local computer to reconnect to the Web UI via the LAN or WAN port (See “Connecting to the Web UI and the CLI”). Note that resetconfig resets the port mappings to factory default, please connect to the correct network port (LAN or WAN) for accessing to Web UI (see Network interfaces and port mapping).

resetconfig provides two optional parameters, ip_address/netmask and @port, to specify a LAN port address and a LAN port mapping (map the LAN port to the specified physical port) while resetting the configurations. All the configurations will be reset to factory default and the LAN settings will be configured to the specified value, so that users can reconnect to Web UI via this port without changing network topology. Furthermore, a static routing entry can be specified to the FortiWAN appliance, so that you can access Web UI across subnets.

System will re-confirm, press [y] to proceed or [n] to cancel.

<ip_address/netmask<@port>>: The parameter in specifying the network configuration ip_ address/netmask to network port @port. The network configuration will be assigned to LAN port by default if parameter @port is not specified.

<network_ip/networkmask@gateway_ip>: The parameter in specifying the static routing entry.

Example:

Considering that the LAN port of a FortiWAN 200B appliance is mapped to the first physical port (port1), IP address 192.168.100.1/255.255.255.0 is assigned to the LAN port and a static routing rule is created to route packets destined to 192.168.200.0/255.255.255.0 to 192.168.100.254. Administrators in

192.168.100.0/255.255.255.0 and 192.168.200.0/255.255.255.0 can access Web UI via the LAN port. Here are the usages of command resetconfig in different ways:

Type “resetconfig [IP address/Netmask]” to specify IP configuration to LAN port from resetting system to factory default.

  • resetconfigresets all the configurations to factory default including LAN settings. In the default port mapping, port1 is mapped to WAN and port4 is mapped to LAN. IP address of the LAN port returns to

192.168.0.1/255.255.255.0. Administrators in 192.168.100.0/255.255.255.0 and 192.168.200.0/255.255.255.0 can not access to Web UI until appropriate changes to cable installation and network topology are done manually.

  • resetconfig 192.168.100.1/255.255.255.0 resets system to factory default, but set

192.168.100.1/255.255.255.0 to LAN port. However, without a specifying, port1 is mapped to WAN and port4 is mapped to LAN by default. Besides, the static routing rule for responding access requests coming from 192.168.200.0/255.255.255.0 is deleted as well. Therefore, it still requires manual changes to cable installation and network topology for administrators in 192.168.100.0/255.255.255.0 and 192.168.200.0/255.255.255.0 can access the Web UI.

  • resetconfig 192.168.100.1/255.255.255.0@port1 resets system to factory default, but map port1 to LAN and set 192.168.100.1/255.255.255.0 to the LAN port. Administrators in 192.168.100.0/255.255.255.0 can access Web UI via the LAN port without any change, but administrators in 192.168.200.0/255.255.255.0 can not access the Web UI until a correct routing rule is created.
  • resetconfig 192.168.100.1/255.255.255.0@port1

192.168.200.0/255.255.255.0@192.168.100.254 resets system to factory default, but map port1 to

LAN, set 192.168.100.1/255.255.255.0 to the LAN port and create a routing rule for packets destined to

192.168.200.0/255.255.255.0, where 192.168.100.254 is the router connecting subnets

192.168.100.0/255.255.255.0 and 192.168.200.0/255.255.255.0. Administrators in 192.168.100.0/255.255.255.0 and 192.168.200.0/255.255.255.0 so that can access Web UI via the LAN port without any change to network deployment.

Note that executing resetconfig without specifying the LAN port settings will reset port mapping to factory default, which implies the WAN links assigned to the default WAN ports are enabled. However, except the LAN port, there will be not port mappings set for WAN and DMZ if resetconfig is executed with specifying any parameter. In the case, there will be not default WAN and DMZ ports available (no default WAN links neither) after resetconfig, administrators have to re-login to Web UI via the LAN port to set the port mappings (see Connecting to the Web UI ).

Tunnel Routing Related – [generic-receive-offload-<port>]

generic-receive-offload-<port>

sysctl generic-receive-offload-<port>=<0|1|default>

Disabling GRO (General Receive Offload) mechanism on the corresponding LAN ports and/or DMZ ports of a Tunnel Routing network can enhance the Tunnel Routing transmission performance (see How the Tunnel Routing Works and How to set up routing rules for Tunnel Routing).

generic-receive-offload-<port>: Enable [1] or disable [0] GRO (General Receive Offload) mechanism on the specified physical network interface <port>, where <port> is a variable. Type default to set the GRO on <port> to default, which is enabled.

<port>: Specify an network interface (port) of FortiWAN in format port#, e.g. port1, port2 and etc.

Example:

sysctl generic-receive-offload-port1=0 disables GRO mechanism on network interface port1.

sysctl generic-receive-offload-port2=default set GRO mechanism on network interface port2 to default, which is enabled.

Note that disabling GRO module on a network port can enhance the Tunnel Routing transmission performance on the port, but it also results in slight impact to non-Tunnel-Routing transmission on the port when the system is under heavy loading (there might be a slight decrease in transmission performance of non-Tunnel-Routing traffic through the network port). We suggest keeping GRO modules enabled on the network ports that does not participate in the Tunnel Routing transmission.

sysinfo: Display usage FortiWAN’s CPU, memory and disk

sysinfo

<port>: The parameter in specifying an network interface (port) of FortiWAN in format port#, e.g. port1, port2 and etc.

For details of the options and parameters, please refer to http://www.tcpdump.org/tcpdump_man.html. Note that options not listed here are not supported by FortiWAN.

traceroute: Shows the packet routes between FortiWAN’s port to a specified destination

traceroute <hostname> <link> <index>

Show the packet routes between FortiWAN’s ports to the hostname.

<hostname>: The parameter in specifying the target IP address or domain name. Note that domain name is valid only if parameter <link> is specified as “wan”.

<link>: The parameter in specifying the link or ports that the traceroute packets start from. The valid values are “wan”, “dmz” and “lan”.
