Optional Services Bandwidth Management
Idle Hour Set-
tings
This is the bandwidth allocation on a WAN link during
defined idle hour (see System > Busyhour Settings for more
details, "
Busyhour Settings
"). Associated traffic passing
through the WAN link during the time period will be shaped
according to the following settings.
Guaranteed Kbps
The guaranteed bandwidth for this class. This secures band-
width allocated as defined for WAN link in peak hours. This
is significant to guarantee the service quality especially for
critical applications like VoIP.
Max Kbps
The maximum bandwidth for WAN link. Maximum band-
width is often allocated to services like WWW and SMTP
that consume large bandwidth. Note that traffic of the WAN
link would be blocked if value of the field is zero.
Priority
The priority of the connections on the WAN link. It can be
High, Normal, or Low. The connections with higher priority
will first be allocated bandwidth.
Inbound & Outbound IPv4/IPv6 Filter
A filter is used to evaluate the traffic passing through FortiWAN by its source, destination and service. Traffic matches
the filter will be associated to the corresponding BM class, so that the traffic is shaped according to the bandwidth
allocation of the class. The source and destination here mean the actual initiator and terminator of the
inbound/outbound traffic, no matter whether the traffic is processed by NAT or Virtual Server.
E Check the box to enable the rule.
Source The source used to evaluate traffic (original packets) by where it comes from (See
"
Using the web UI
").
Destination The destination used to evaluate traffic (original packets) by where it goes to (See
"
Using the web UI
").
Service
The service used to evaluate traffic (original packets) by what the source port and
destination port they are. Service matches as long as source port or destination
port matches (See "Using the web UI").
The options GRE and ESP in the Service drop-down menu is for the GRE and
ESP packets coming from other VPN devices. GRE and ESP packets generated
by FortiWAN are invisible to Bandwidth Management filters.
Classes The BM class that traffic matching the filter (Source, Destination and Service) is
associated with.
L Check to enable logging: Whenever the rule is matched, system will record the
event to log file.
