Bandwidth Management (rate limiting)

Enable bandwidth rate

limiting

Select this option to specify bandwidth rate limiting for the access

speed for outbound (upload) traffic and inbound (download) traffic

across the device. Applying bandwidth limitation physically limits the

rate of traffic flow. You can define separate limits for outbound and

inbound traffic in kbps.

Note Bandwidth Management is typically used to

prevent packet queuing on a WAN device to provide lower

end-to-end latency on latency sensitive traffic such as

voice over IP.

Network Protection

If you configure Network Protection options, verify that all IP hosts that use the zone are within the

IP addresses specified. Hosts may include:

• directly attached hosts connected to the zone via the Ethernet ports associated with the zone

• remote IP subnets connected via routers in the zone

• IP Address pools specified for any PPTP or L2TP server where the VPNs terminate in the security

zone.

This option is commonly used for transparent deployments to ensure that an IP address can appear

in only one security zone.

IP Address Restrictions The IP addresses for this security zone, either an IP Address Group,

IP subnet or IP range.

Note If you do not specify any restriction, the device will

automatically learn the IP addresses of clients in each

Security Zone.

Prevent Security Zone

sending to VPN tunnels

Determines whether traffic is allowed from this security zone to an

IPSec VPN tunnel.
