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. If the application uses a single port number, enter it in both fields.
HotBrick Network Solutions 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.
HotBrick Network Solutions Settings – Dynamic DNS Dynamic DNS Service 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).

HotBrick Network Solutions 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.
HotBrick Network Solutions Settings – Multi DMZ Enable Use this to enable or disable the DMZ setting, as required. Name Enter a name to assist you to remember this setting. This name has no effect on the operation. For Static IP Public IP address Enter the WAN port (Internet) IP address you wish to associate to a PC. This IP address must have been allocated to you by your ISP. Private IP Address (LAN) Enter the IP address of the PC you wish to associate with this WAN port IP address.
HotBrick Network Solutions 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 20 UPnP Settings – UPnP UPnP Option If you Enable UPnP, then this two wan router will become one of the entire local network. You can find out there is an icon show up on network neighborhood on the window XP OS.
HotBrick Network Solutions Advanced Features This screen allows you to change some advanced settings: • NAT – NAT (Network Address Translation) is the technology which allows a number of LAN PCs to share one (1) Internet IP address. These settings rarely need to be changed. • Remote Access Configuration – This feature allows you to manage the Load Balancer via the Internet. You can restrict access to a specified IP address or address range.
Session Persistency (Protocol, Port Range) Enabled Session 1 Session 2 BOTH 0 ~ Session 3 BOTH 0 0 ~ BOTH 0 0 ~ Session 4 Session 5 BOTH 0 0 ~ Session 6 BOTH 0 0 ~ BOTH 0 0 ~ 0 Session Persistency – Some Internet applications (notably secure web sites, gaming sites) would need several established sessions to make a successful transaction (or connection) and most likely they expect all sessions would be coming from the same source (IP address).
HotBrick Network Solutions Remote Access Configuration • Remote Upgrade – If enabled, you can use the supplied Windows program to remotely upgrade the Firmware. If not enabled, upgrades must be performed by a PC on the LAN. • Remote Web-based setup - – If enabled, access to the Web-based interface is available via the Internet. (See below for details.) If not enabled, access is only available to PCs on the LAN. • Port – The port number used when connecting remotely. See below for details.
HotBrick Network Solutions Interface Binding SMTP (Simple Mail Transport Protocol) Binding Unless you are using E-mail accounts from different ISPs on each port, you can ignore these settings. Some ISPs configure their E-mail Servers so they will not accept E-mail from IP addresses not allocated by themselves. If you are using accounts from different ISPs, sending E-mail over the wrong port may result in non-acceptance of the mail. In this case, you can use these settings to correct the problem.
HotBrick Network Solutions 5: Security Management Overview • Block URL 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.
