192.168.10.0/255.255.255.0 ANY No PR
211.21.48.196 10.10.1.0/255.255.255.0 No PR
Note: Rules are matched top down. Once one rule is matched, the rest will be ignored. In this case, the connections
from 192.168.0.15 may meet the criteria of the first and second IP Pair rules, only the first rule will be applied. Hence
the rules will not perform NoPR on 192.168.0.15 even though it matches the second rule.It shall be noted that Web
Service Rules are prioritized over IP Pair Rules. As 192.168.10.0/255.255.255.0 is configured to be NoPR in IP Pair
Rules, but DoPR in Web Service Rules, HTTP connections will still apply persistent routing.
Bandwidth Management
Bandwidth Management (BM) allocates bandwidth to applications. To secure the bandwidth of critical applications,
FortiWAN Bandwidth Management (BM) defines inbound and outbound bandwidth based on traffic direction, i.e. take
FortiWAN as the center, traffic flows from WAN to LAN is inbound traffic, otherwise, it is outbound traffic. The section
will mainly explain how to guarantee bandwidth based on priority settings, and how to manage inbound and outbound
traffic by configuring busy/idle hours, data source/destination, and service type, etc.
Bandwidth Management consists of Classes and IPv4/IPv6 Filters. Click "Expand Link Settings" or "Collapse Link
Settings" to show or hide configuration details of links and bandwidth limit.
FortiWAN provides mechanisms to record, notify and analysis on events refer to the Bandwidth Management service,
see "Log", "Statistics: Bandwidth" and "Report: Bandwidth Usage".
