AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Chapter 4: Advanced Menu This menu allows advanced configuration options for your router. Figure 7: Advanced menu WAN Wide Area Network refers to the configurations you perform to establish an Internet connection. There are several types of WAN connections that require different settings. Wide Area Network (WAN) is also referred to as the broadband connection. Connection settings differ for every service provider.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 19 Figure 8: New PPPoE Connection Setup PPPoA Connection PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets in ATM cells that are carried over the DSL connection. PPP or Point-to-Point Protocol, is a method of establishing a network connection/session between network hosts. It usually provides a mechanism for authenticating users.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Static Connection Static connection type is used whenever a known static IP address is assigned to the router. Additional addressing information such as the subnet mask and the default gateway must also be specified. Up to three Domain Name Server (DNS) addresses can be identified. These servers resolve the name of the computer to the IP address mapped to it and thus enable you to access other web servers by typing the symbolic name (host name).
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 21 Bridge Connection A pure bridged connection does not assign any IP address to the WAN interface. NAT and firewall rules are not enabled. This connection method makes the router act as a bridge for passing packets between the WAN interface and the LAN interface.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual ADSL Modulation ADSL Modulation allows you to select any combination of DSL training modes. Leave the default values if you are unsure or the service provider did not provide this information. In most cases, this page should not be modified.

AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Quality of Service Quality of Service allows network administrators to configure the routers to meet the real time requirements for voice and video. Different networks use different QoS markings like: • ToS network: ToS bits in the IP header • VLAN network: priority bits in the VLAN header • DSCP network: uses only 5 bits of the CoS • WLAN: WLAN QoS header. The QoS framework is supported on all the above domains.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 37 No Egress The default Egress page setting for all interfaces is No Egress. In this mode, the domain mappings of the packets are untouched. Figure 27: Egress Layer 2 Egress The Egress Layer 2 page allows you to map the CoS of an outgoing packet to user priority bits, which is honored by the VLAN network. Again, this feature is only configurable on the WAN interface as VLAN is only supported on the WAN side in the current release.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Field Interface Unclassified Packet Class of Service User Priority Description Select the WAN interface to configure the QoS for outgoing packets; LAN interface cannot be selected as VLAN is currently supported on the WAN side only. Some locally generated packets might not have been classified and thus do not have a CoS value, such as PPP control packet and ARP packet.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 39 There are four Ingress modes: • Untrusted mode • Layer 2 • Layer 3 • Static Untrusted Mode Untrusted is the default Ingress page setting for all interfaces. In this mode, no domain mapping is honored in the router. All packets are treated as CoS6 (best effort).
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Layer 2 Ingress Layer 2 allows you to map an incoming packet with VLAN priority to CoS. This feature is only configurable on the WAN interface as VLAN is only supported on the WAN side in the current software release. Figure 31: Layer 2 Ingress Field Interface Class of Service User Priority Description Select the WAN interface here to configure the CoS for incoming traffic.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 41 Layer 3 Ingress The Layer 3 page allows you to map ToS bits of incoming packets from the IP network to CoS for each WAN/LAN interface. Figure 32: Layer 3 Ingress Field Interface Class of Service ToS Default Non-IP Description For both WAN and LAN interfaces, you can configure QoS for layer 3 (IP) data traffic.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Static Ingress The Ingress - Static page enables you to configure a static CoS for all packets received on a WAN or LAN interface. Figure 33: Static To configure Ingress Static: 1. 2. 3. 4. 5. 6. 7. 8. Select Advanced menu. Select QoS > Ingress. Select the quickstart interface. Select Static. At the ETHERNET Interface. You are configuring QoS on this interface only. Any WAN/LAN interface that is not configured has the default Untrusted mode.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 43 Figure 34: QoS Shaper Configuration Field Interface Max Rate HTB Queue Discipline Low Latency Queue Discipline PRIOWRR Egress TCA is required if shaper is configured for that interface. Description The selections are WAN/LAN interfaces except WLAN, which does not support Shaper feature. This field needs to be selected before shaper configuration.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Example 1: HTB Queue Discipline Enabled In the example below, HTB Queue Discipline is enabled. The PPPoE1 connection has a total of 300Kbits of bandwidth, of which 100Kbits is given to CoS1 and another 100Kbits is given to CoS2. When there is no CoS1 or CoS2 packet, CoS6 packets have the whole 300Kbits of bandwidth.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 45 CoS1 is not rate controlled (hence the field is not displayed). When there is no CoS1 packet, CoS2, CoS3, CoS4 each has 10% and CoS6 has 70%. This is similarly to the Low Latency Queue discipline, except that one is packet-based and the other is rate-based. Figure 37: PRIOWRR enabled Policy Routing Configuration The Policy Routing Configuration enables you to configure policy routing and QoS.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Field Ingress Inter face Destination Interface DiffServ Code Point Class of Service Source IP Mask Destination IP Mask Protocol Source Port Destination Port Source MAC Local Routing MAC Description The incoming traffic interface for a Policy Routing rule. Selections include LAN interfaces, WAN interfaces, Locally generated (traffic) and not applicable.
AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual 47 The following fields can be configured for Policy Routing: • Destination IP address/mask • Source IP address/mask • Source MAC address • Protocol (TCP, UDP, ICMP, etc) • Source port • Destination port • Incoming interface • DSCP Routing Static Routing If the router is connected to more than one network, you may need to set up a static route between them.
AT-AR256E v3 - 4 Ports ADSL2/2+ Router - User Manual Routing Table Routing Table displays the information used by routers when making packet-forwarding decisions. Packets are routed according to the packet's destination IP address. Figure 40: Routing Table System Password Anyone who can access the Web User Interface can be considered an Administrator.
