6.2.7 FTP ALG Configuration

Most FTP servers allow the capability of listening on a non standard control port other than

TCP 21. When the policy associated with this non standard port is configured with the

application ftp qualifier, as configured in the solution to this recipe, it dynamically open the

pinholes for the data channel for such FTP sessions.

Advanced users can use this feature for outgoing traffic, creating "NAT IP MAPPING" rules that

divert all traffic that is destined for a certain IP address to a different IP address.

Entries in this table allows you to configure one Global IP Pool for specified Local IP address

from LAN.

6.3 QoS

6.3.1 IP QoS

The DSL device provides a control mechanism that can provide different priority to different users

or data flows. The QoS is enforced by the QoS rules in the QoS table. A QoS rule contains two

configuration blocks: Traffic Classification and Action. The Traffic Classification enables you to

classify packets on the basis of various fields in the packet and perhaps the physical ingress port.

The Action enables you to assign the strict priority level and mark some fields in the packet that

matches the Traffic Classification rule. You can configure any or all field as needed in these two

QoS blocks for a QoS rule.

Fields on the first setting block of this page:

Field

Description

IP QoS

Enable/Disable the IP QoS function.

Source IP

The IP address of the traffic source.

Source Netmask

The source IP Netmask. This field is required if the source IP has been entered.

Destination IP

The IP address of the traffic destination.

Destination Netmask

The destination IP Netmask. This field is required if the destination IP has been

entered.

Protocol

The selections are TCP, UDP, ICMP and the blank for none. This field is required if

the source port or destination port has been entered.

classification rule.

IP Type of Service
