Tunnel Routing
Load Balancing & Fault Tolerance
Bandwidth Management
Tunnel Routing is designed to be transparent to FortiWAN's Bandwidth Management (See "
"). The way to allocate or limit bandwidth to traffic of Tunnel Routing is to drill it down to the original
packets, control the traffic by individual service, source or destination. In other words, the traffic of individual service
transferred through Tunnel Routing can be controlled. Guaranteeing proper bandwidth to individual traffic helps for the
performance of Tunnel Routing transmission. Packets encapsulated by Tunnel Routing becomes invisible to
Bandwidth Management; controlling the overall Tunnel Routing traffic by service GRE will go to failure.
FortiWAN provides mechanisms to record, notify and analysis on events refer to the Tunnel Routing service, see "

How to set up routing rules for Tunnel Routing
Tunnel Routing - Setting
There are two major steps to set up Tunnel Routing,
define the association of tunnels
(see the tables:
Basic
Setting
and
Tunnel Group
) and
set up the routing rules
(see the tables:
Default Rules
,
Routing Rules
and
Persistent Rules
). Tunnel Routing works in symmetric FortiWAN sites, when the unit we are talking about or
configuring to is called
local host
(or local site), the opposite unit is then called
remote host
(or remote site).
Basic Setting
The basic settings are located here: enabling or disabling Tunnel Route logging, define names and entering tunnel
routing activation key (if the encryption function is enabled for a tunnel group).
Tunnel Route Log
:
Enable or disable logging. FortiWAN provides mechanisms to record, notify and analysis
on events refer to the Tunnel Routing service, see "
", "
", "
" and "
".
Local Host ID
:
Assign a
unique
host name for this unit. Tunnels are established between two FortiWAN
units. Host ID is used for Tunnel Routing to recognize the units running TR transmission.
Symmetrically, this field is required to the opposite unit.
Key
:
Decide a secret key for tunnel encryption and enter it here, if the encryption function is
enabled for a tunnel group. Tunnel Routing encryption employs only one secret key for all
tunnel transmissions, therefore, please set the decided key to all the tunnel routing hosts.
This key is used for the data encryption built in Tunnel Routing, not for encryption of IPSec.
For an IPSec protection on Tunnel Routing, please refer to "
