Session Limit

This new feature allows to drop the new sessions from both WAN and LAN side. If the new

sessions number are exceed the maximum sessions in a sampling time.

Figure 24: Session Limit

Session Limit

Sampling Time

The period to count the new session. Only those new sessions

occurred in the most recently sampling time were be count for limit

checking.(Default is 400 mil-sec)

Maximum of Total New

session

If the number of new sessions for system exceed the maximum in the

Sampling Time. Any new sessions in the system will be dropped.

(Default: 65535 session/sec)

Maximum of New

Sessions for Host

If the number of new sessions for the host exceeds the maximum in the

sampling time. Any new session of the host will be dropped. (Default:

session/sec)

Maximum of Dropped

New Sessions for Host

If the number of dropped new sessions for the host exceeds the

Maximum in the sampling time, any new session of the host will be

dropped for the pause time.

Pause Time

Within the pause time, no new session of the suspended host could be

served by system.( Default is 5 minutes)

Firewall Exception

System Firewall Exception Rules: The rules with which any received packets is complied, the packets

will not processed by Firewall or NAT module, but to be processed directly by system protocol stack.

Figure 25: Firewall Exception

Firewall Exception

Enable

The check box can allow you enable or disable firewall exception.

Interface

You can select LAN, WAN1, WAN2 or ALL interfaces to be process by

the system protocol stack. If you enable check box.

Protocol

There are six protocols (UDP/TCP/ICMP/GRE/ESP/AH) to choose to let

packets directly process by the system protocol stack.

Foreign Port Range

Select foreign port number range directly process by system protocol

stack. If enable check box.

Device Port Range

Select device port number range directly process by system protocol

stack. If enable check box.

6: QoS Configuration

Overview

The

Load Balancer provides QoS, which supports the high quality of network service.

Because it will classify outgoing packets based on some policies defined by users, make some

real-time applications to get better response or performance.

QoS Setup

The following web page management are guiding you how to setup QoS and make QoS work.

Figure 26 QoS Setup

Data – QoS Setup.

QoS Feature

±

Enable QoS

– This will allow users enable QoS function.

•

Queuing Method

– The methods that how you manage your queue.” Priority

queuing”. It is one of the first queuing variations to be wildly implemented.

IP TOS ( Type

of Service)

Feature

•

Process TOS Field

–An 8 bits field in the IP packet header designed to

contain values indicating how each packet should be handled in the network.

If you choose "enable" then it will enable this function to process IP Type of

Service field.

•

Overwrite policy priority

– Choose “yes” to set the priority of TOS field in IP

packet overwrite the priority defined in policy configuration

Policy Configuration

When you use QoS, you must define some policies to make some packets to have higher priority

to pass through.

Admission

Policy

This section identifies each policy

•

Policy Name List

– When adding a new Policy, ignore this list. To edit an

existing entry, select it from the list, and click the "Select" button. The data

fields will then be updated with data for the selected entry.

•

Policy Name

– Enter a suitable name. Generally, you should use the "Policy

Name" for the network traffic.

•

Source Address

– Define the source address of packets here. It has two

types like IP address or MAC address. If you select IP address, you can

define IP address range, otherwise define up to four MAC addresses.

•

Destination Address

– Define the destination address of packets here. The

explanation is as the same as above.

•

Protocol Type

– The field defines traffic packet type, i.e. IP,TCP and UDP.

•

Source Port

– Define the source port of packets here.

•

Destination Port

– Define the destination port of packets here.

•

Priority Queue

– It defines a packet if it meets all conditions defined above, it

will be serviced with some priority level.
