Setup is now completed. Accessing AOL To access AOL (America On Line) through The Load Balancer, the AOL for Windows software must be configured to use TCP/IP network access, rather than a dial-up connection. The configuration process is as follows: • Start the AOL for Windows communication software.
• Set your Default Gateway to the IP Address of The Load Balancer. • Ensure your DNS (Name server) settings are correct. To act as a DHCP Client (recommended) The procedure below may vary according to your version of Linux and X -windows shell. 1. Start your X Windows client. 2. Select Control Panel - Network 3. Select the "Interface" entry for your Network card. Normally, this will be called "eth0". 4. Click the Edit button, set the "protocol" to "DHCP", and save this data. 5.
3: Advanced Port Setup Overview • Port Options contains some options, which can be set on either or both WAN ports. For most situations, the default values are satisfactory. • Load Balance screen is only functional if you are using both WAN ports. It allows you to determine the proportion of WAN traffic sent through each port. • Advanced PPPoE setup is required if you wish to use multiple sessions on one or both of the WAN ports. It can also be used to manually connect or disconnect a PPPoE session.
Settings – Port Options Interface Connection Health Check • WAN Ports – To select the WAN port for option settings • MTU –The largest amount of data that can be transferred across a given physical network. Ethernet limits transfers to 1500 octets of data. Normally, you should leave this value at its default value. Change it only if the ISP is providing a MTU that is not optimal • Method – ICMP: The health check is performed by sending an ICMP echo request packet to the specific destination.
Transparent Bridge Option (for all interface) • Traffic Management – Strict binding: Traffic from bridge hosts (eg. transparent to WAN1) can only go through that a specified WAN (eg. WAN1) interface. Loose binding: Traffic from bridge hosts (eg. transparent to WAN1) can go through an alternative WAN (eg. WAN2) interface when binded interface (eg. WAN1) is down. It acts like a failover mechanism for Transparent Bridge mode. Load Balancing: Traffic from bridge hosts (eg.
Load Balance This screen is only operational if using Internet connections on both WAN ports. Figure 3-2: Load Balance These settings are only functional if using both WAN ports. If using both WAN ports, these settings determine the proportion of traffic sent over each port.
Settings – Load Balance Load Balance Configuration • Enable – This will allow you enable or disable the load-balancing feature. • Load Balancing Base On – Select the desired option to measure the traffic load. 1. Bytes Tx + Rx: The link with the least number of bytes transmitted through the WAN port. 2. Packets Tx + Rx: The link with the least number of packets transmitted through the WAN port. 3. Sessions Established: The link with the least number of sessions built on the WAN port. 4.
Advanced PPPoE The screen is required in order to use multiple PPPoE sessions on the same WAN port. It can also be used to manually connect or disconnect a PPPoE session.

Advanced PPTP This screen is only useful if using the PPTP connection method. Figure 3-4: Advanced PPTP Settings – Advanced PPTP WAN Port WAN IP Account Used if you choose PPTP on Static/Dynamic IP as your connection setup from primary setup.
PPTP Auto Dialup Connection Status • Auto Dialup –To enable or disable auto dialup for a PPTP connection. If you decide not to use auto dialup or auto disconnect, then you have to connect/disconnect manually. • Disconnect After Idle –To decide the timeout for disconnecting when there is no traffic on the connection. Enter -1 to keep the connection always alive. Enter 0 to enable 'dial on demand by trigger'. • Echo Time –To determine how often an Echo request is sent to the PPTP server.
4: Advanced Configuration Overview The following advanced features are provided. • Host IP Setup • Routing • Virtual Servers • Special Applications • Dynamic DNS • Multi DMZ • UpnP • NAT Setup • ARP Statp • Advanced Features This chapter contains details of the configuration and use of each of these features. Host IP Setup This feature is used in the following situations: • You have Multi-Session PPPoE, and wish to bind each session to a particular PC on your LAN.
Figure 4-1: Host IP Setup Settings – Host IP Setup Host Network Identity This section identifies each Host (PC) • Host name – Enter a suitable name. Generally, you should use the "Hostname" (computer name) defined on the Host itself. • MAC Address – Also called Physical Address or Network Adapter Address. Enter the MAC address of this host. • Select Group – Select the group you wish to put this host into.
Host Network Binding • Bind WAN port/Session – Select Enable if you wish to associate this PC with a particular PPPoE Session. All traffic for that PC will then use the selected PPPoE port and session. • Binding Method – Suppose your PC is bound to WAN1 port, now you are selecting “Strict Binding”. If WAN1 port is disconnected, your packets cannot go out through WAN2 port, if WAN2 port is still alive.
Note: If there is an entry or entries in the Routing table with an Index of zero (0), these are System entries. You cannot modify or delete these entries. Settings – Routing Dynamic Routing Static Routing Routing List • RIP v2 – RIP is a dynamic routing protocol which is used to direct traffic over the network. Disable it if you don't need to use it. • LAN, WAN1, WAN2 – If enabled, any WAN or LAN can execute RIP function.
Static Routing - Example Segment 1 (192.168.2.xx) (192.168.2.80) (192.168.1.100) Segment 0 (192.168.1.xx) Router A (192.168.1.1) Router B (192.168.2.90) (192.168.3.70) Segment 2 (192.168.3.xx) Figure 4-3: Routing Example For The Load Balancer Gateway's Routing Table For the LAN shown above, with 2 routers and 3 LAN segments, The Load Balancer requires 2 entries as follows. Entry 1 (Segment 1) Destination IP Address 192.168.2.0 Network Mask 255.255.255.0 Gateway IP Address 192.168.1.
For Router B's Default Route Destination IP Address 0.0.0.0 Network Mask 0.0.0.0 Gateway IP Address 192.168.2.80 Interface LAN Metric 3 Virtual Servers This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: • Your Server's IP address is only valid on your LAN, not on the Internet. • Attempts to connect to devices on your LAN are blocked by the firewall in The Load Balancer.
Connecting to the Virtual Servers Once configured, anyone on the Internet can connect to your Virtual Servers. They must use The Load Balancer's Internet IP Address (the IP Address allocated by your ISP). e.g. http://205.20.45.34 ftp://205.20.45.34 • To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP. • This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers.
Settings – Virtual Server Virtual Server Configuration Virtual Server List • Enable – To activate or deactivate the current entry. • Server Name – A unique name for identifying the virtual server. • Protocol – Select the protocol (either TCP or UDP) used by the server software. • IP Address – LAN: Enter the IP address of the server on the device's LAN side. The hosts used as Virtual Servers need static IP addresses or reserved IP addresses. WAN: The WAN port that the virtual server is bound on.
Special Applications If you use Internet applications, which have non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the firewall in The Load Balancer. In this case, you can define the application as a "Special Application" in order to make it work.
Settings – Special Applications Special Application Configuration Special Application List • Enable – Use this to Enable or Disable this Special Application as required. • Name – Enter a descriptive name to identify this Special Application. • Outgoing Protocol –Select the protocol used by this application, when sending data to the remote server or PC. • Outgoing Port Range – Enter the beginning and end of the range of port numbers used by the application server, for data you send.
Dynamic DNS Dynamic DNS is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect to your ISP, which makes it difficult to connect to you. You must register for the Dynamic DNS service.
Settings – Dynamic DNS Dynamic DNS Service Additional Settings WAN Port Binding Use this to Enable/Disable the Dynamic DNS feature, and select the required service provider. • Disable – Dynamic DNS is not used. • TZO – Select this to use the TZO service (www.tzo.com). You must configure the TZO section of this screen. • Standard Client – Select this to use the standard service (from www.dyndns.org or other provider). You must configure the Standard Client section of this screen.
Multi DMZ This feature allows each WAN port IP address to be associated with one (1) computer on your LAN. All outgoing traffic from that PC will be associated with that WAN port IP address. Any traffic sent to that IP address will be forwarded to the specified PC, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet users or Servers. Note: The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks.
Settings – Multi DMZ Multi DMZ Edit • Enable – To activate or deactivate the current DMZ entry. • WAN – The WAN (WAN1, WAN2) port applied to the current DMZ entry. • Name – To identify the current DMZ entry. • Public IP –The public IP (or PPPoE session) that the current DMZ entry is bound on. • Private IP (LAN) –The IP address of the server in the DMZ • Access Group –To specify which Access Group will be applied. Each Access Group has its own access rules.
UPnP With UPNP (Universal Plug & Play) function, it can easily setup and configure an entire network, enable discovery and control of networked devices and services. Figure 4-9: UPnP Settings – UPnP UPnP Option • UpnP (Univeral Plug & Play) can be enabled or disabled for automatic device configuration. If disabled (Default), the router will not allow any device to automatically control the resources.
UpnP Port Mapping List You can set the dynamic port mappings to Internet gateway via UPnP on Windows XP.
NAT NAT (Network Address Translation) is the technology which allows one (1) WAN (Internet) IP address to be used by many LAN users. Figure 4-10: NAT Settings – NAT NAT Configuration • NAT Routing –Enables or disables NAT routing by checking or un-checking the checkbox. If you disable NAT routing, this device will act as a Bridge or Static Router. Most features, including Load Balance, will be unavailable.
NAT Port Option NAT Alias NAT Alias List • Non-Port-Translation –To keep the source port number unchanged for TCP/UDP sessions on the specified Port Range. Some special applications do not allow the source port number to be translated. • Port Range – The Source Port Number Range for TCP and UDP protocol. • Specific TCP / UDP Timeout –To define specific Timeout for TCP/UDP sessions on the specified Port Range.
ARP Status ARP (Address Resolution Protocol) – This is web page is regarding LAN & WAN ARP statistics and information, Figure 4-11: ARP Table • Requests ( In / Out ) – The numbers of system ARP sent to requests. • Reply ( In / Out ) –The numbers of system ARP reply to. • System Time – System starting time. • Global Arp Ageout Time – Arp time out. By default is 600 seconds. If set to “0” means no expire. Arp Table • List all LAN, WAN address resolution and its related info.
Advanced Features • External Filters Configuration –To limit the packets passing through the device from WAN side to LAN side • DNS Loopback – If there is any domain in your private network you can setup the Domain Name & Private IP mapping table for DNS query. • Protocol & Port Binding – It is similar to SMTP binding but you must setup additional data such as Protocol & Port Range. If all the checking items are met, the packet will be bound on the specified WAN port.
Settings – Advanced Features External Filters Configuration • DNS Loopback When you have some servers on LAN and their domain names have already registered on public DNS. To avoid DNS loopback problem, please enter the following fields. Application Protocol & Port Binding Block Selected ICMP Types –This acts as "master" switch. If checked, the selected packet types are blocked. Otherwise, they are accepted. • Domain Name – Enter the domain name specified by you for local host/server.
5: Security Management Overview • URL Filter It can block specific website by configure IP address, URL or Key words • Access filter You can block all Internet access or select block well-known port or block user define ports by groups. • Session Limit It can eliminate users access Internet, and send email alert to the administrator. If the device detect new sessions that is exceed the maximum sampling time.
Settings – URL Filter Access Group • Select Group – A group that current rule is applied for • URL Filter Type –The Filter type (Block/Allow) that current group is set to use.

Appendix C Troubleshooting Overview This chapter covers some common problems that may be encountered while using The Load Balancer and some possible solutions to them. If you follow the suggested steps and The Load Balancer still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to The Load Balancer to configure it. Solution 1: Check the following: • The Load Balancer is properly installed, LAN connections are OK, and it is powered ON.
Solution 2: The Load Balancer processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applications which do not function correctly. If this does solve the problem you can use the DMZ function. This should work with most applications, but: • It is a security risk, since the firewall is disabled for the DMZ PC. • Only one (1) PC can use this feature.
