Fixed (Static) IP The Public IP Address and Subnet Mask of the Corega BAR-SD Router are used by external users of the internet (including your ISP). If you have been assigned a Fixed IP address by your ISP, select this item and enter the IP Address and Subnet Mask provided. •Specify WAN IP Address:Enter the IP address provided by your ISP. •Subnet Mask:Enter the Subnet Mask values provided by your ISP. •Default Gateway IP Address:Your ISP will provide you with the Default Gateway IP Address. This is sometimes called the ‘Next-hop’. •Domain Name Server (DNS):Your ISP will provide you with at least one DNS IP Address. Multiple DNS IP settings are common. The first available DNS entry is used in most cases. PPTP This is a ‘dial-up type’ connection type provided by some ISPs. •LAN IP Address:Enter the IP address of the router (default = 192.168.123.254) •My IP Address:The IP address of the PPTP Client you want to negotiate with the PPTP server. •My Subnet Mask:The subnet mask of the PPTP Client •Server IP Address:The address of the PPTP Server •PPTP Account:The login name on the PPTP Server •PPTP Password:The password of the user account ENGLISH 10
11 Basic Settings This section allows users to configure the WAN manually. PPPoE •LAN IP Address:Enter the IP address of the router (default = 192.168.123.254) •Account: Enter your User Name provided by your ISP. Leave this blank if you have not been given a User Name by your ISP. •Password:Enter your Password provided by your ISP. •Specify DNS Server Address: Your ISP will provide you with at least one DNS IP Address. Multiple DNS IP settings are common. The first available DNS entry is used in most cases. •Maximum Idle Time: If Dial-on-demand is enabled, this parameter is the number of minutes that the WAN connection is kept active after the last data was sent. When this time period is exceeded, this WAN link will be dropped. This feature ensures that when frequent data traffic is sent or received by the WAN link, that the Dial-on-demand startup delay does not impede the throughput for the user. Setting this to 0 will disable this feature. •Auto-reconnect:If this box is left blank, then the connection will always be active. If the box is checked, then the router will start a WAN connection whenever there is data to be transferred. This allows the router to be used with ISP accounts when the ISP bills per second of usage.

This allows the router to be used with ISP accounts when the ISP bills per second of usage. DHCP Server DHCP Server. A DHCP (Dynamic Host Configuration Protocol) Server can automatically assign IP Addresses to each computer in your network. Unless you already have a DHCP Server in you LAN, it is highly recommended that you set your router to act as a DHCP server. •Enable DHCP Server: Select “Enable” to use the DHCP server option of the router. If you already have a DHCP server in your network, set the routers DHCP option to “Disable”. •IP Pool Address Range:Enter range of numbers, from 0 to 253, for the DHCP server to use when assigning IP Addresses to the attached LAN devices. •Lease Time:Enter the time that the IP addresses remain valid, before being timed-out buy the router. A recommended value for this setting is 2 hours. •Domain Name: This is an optional entry for a Domain name server, which will be passed to clients on the local LAN. ENGLISH
Change Password •Old Password:If you need to change the password, then you must enter the present password in this box. •Password:If the administrator needs to change the password, type in the new password here. •Re-type Password:If the administrator needs to change the password, this box must match the contents of the password. Virtual Server If you configure the Corega BAR-SD Router as a virtual server, remote users accessing services such as Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP address. In other words, depending on the requested service (TCP/UDP port number), the Corega BAR-SD Router redirects the external service request to the appropriate server. Example: ID Service Port Server IP Enable Comment 180192.168.123.1 Yes Web Server 221192.168.123.2 Yes FTP Server 323192.168.123.3 Yes Telnet Server In the example above, ID=1 allows data sent to the WAN IP address on port 80 to be re-directed to the Web Server at 192.168.123.1 on the local LAN.

15Applications Some applications require multiple connections, such as internet gaming, video conferencing, internet telephony and others. These applications cannot work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, specify the port normally associated with an application in the Trigger Port field, then enter the public ports associated with the trigger port to open them for inbound traffic. Example: ID Trigger Port Public Port Comment 128800 2300-2400, 47624MSN Game Zone 228800 2300-2400, 47624MSN Game Zone 36112 6112 Battle.net Miscellaneous Items IP Address of DMZ Host. Note!To use this application, you should obtain a Fixed (Static) Public IP Address from your ISP. ENGLISH
The DMZ Host application allows unrestricted 2-way communication between a single LAN PC and other internet users or servers. This application is useful for supporting special-purpose services such as video-conferencing and gaming, that require proprietary client software and/or 2-way user communication. Note!That, in order to provide unrestricted access, the Firewall provided by the Corega BAR-SD Router to protect this port is disabled, thus creating a potentially serious security risk. It is recommended that this application should be disabled when it is not in use by entering not checking the “Enable DMZ” field. Non-standard FTP port You have to configure this item if you want to access an FTP server whose port number is not 21. This setting will be lost after rebooting. Packet Filters This blocks outgoing packets. It is therefore useful for example, if you want to allow users access to Web and FTP servers, but not to newsgroups. To block a particular IP address, enter the IP address, and the time and days that you would like the protocols to be blocked. (Note, the Simple Network Time Protocol should be enabled for this to function). Domain Filters Let you prevent users under this device from accessing specific URLs. ENGLISH 16
17URL Blocking URL Blocking will block computers on the LAN ports from connecting to pre-defined websites. •URL Blocking: Check “Enable” or “Disable” to make this function active or inactive. •URL:If any part of the websites URL matches the pre-defined word, the connection will be blocked. For example, you can use the pre-defined word sex to block all websites if their URLs contain the pre-defined word sex. •Enable:Checked to enable each rule. MAC Control The Corega BAR-SD Router provides two MAC Address Control features for up to 32 MAC addresses: •Fixed IP Mapping:This will assign a fixed IP address to a specified client (by MAC address) •Connection Control:This allows or denies clients to connect to this device and the internet. •MAC Address Control:Select ‘Enable’if you want the router to perform a MAC Address Control. •Connection Control:Select ‘Enable’ if you want the router to ‘allow’ or ‘block’ Clients from connecting to the internet. Choose allowor denyto allow or deny clients whose MAC addresses are not listed in the Control table. MAC AddressIndicates a specific clients MAC address. IP AddressExpected IP address of the corresponding client. Leave it blank if you dont want to assign a specified IP address to the corresponding client. CWhen Connection control is enabled, checking C will allow the corresponding client to Connect to this device. ENGLISH
Miscellaneous •Remote Administrator Host:Setting this to ‘Enable’will allow users on the WAN port to manage the router. If the address is set as 0.0.0.0, then any device on the WAN port can become administrator. If a unique IP address is specified, then only a device with the same IP address can access the router via the WAN port. Setting the subnet bits “/nn” will allow a group of administrators to have access. Note!When Remote Administration is enabled, the web server port will be shifted to 88. •Administrator Time-out:If there is no admin activity via the WAN port for X seconds, then the administrator is logged out. Setting this value to zero disables this function. •Discard PING from WAN side:When this feature is enabled, no host on the WAN can ping this product. System Time This allows the Corega BAR-SD Router to synchronise its system clock to an external clock source on the internet. This is useful if the administrator is required to log the router’s actions in real time. •Enable NTP:Checking this box will force the router to synchronise its internal system clock against an external Simple Network Time Protocol server. •Time Server:Enter the IP address of the SNTP server. Alternatively, the time can be set by the PC or manually ENGLISH 18
