P380 Users guide Overview The AP router, P380, is a standalone wireless client, which provides IP routing functionality between a Local Area Network (LAN) and a Wide Area Network (WAN). It uses an Ethernet interface to connect to LAN, and wireless 802.11b-based interface to connect to a Wireless Networking System, which provides miscellaneous WAN access. Wireless Networking System P380 is part of the Wireless Internet Service Provision System.
P380 Users guide Features P380 is based on indoor architecture. An indoor unit with 2.4 GHz antennas is placed on the mast or the ceiling of the construction elements. It is connected to a UTP cable. An individual computer or an entire local network can gain access to the Internet by simply connecting the P380 indoor unit to the switch/hub. P380 is a full featured IP router with extensive firewall capabilities and a user-friendly web interface.
P380 Users guide 3 Operating Modes The P380 Router supports 3 different kind of operating modes: AP-Router, AP and Bridge. AP-Router Mode In this mode, the P380 wireless unit plays the roles of the wireless network Access point and a router. LAN Hub Firewall Wireless LAN WOR-3000 WOR-3000 (ETRAX-100LX) (ETRAX-100LX) link ss ele Wir Wireless endpoint (client) WWW Server Wireless ISP Network Figure 2: AP-Router mode AP Mode In this mode, P380 acts as conventional wireless Access point.
P380 Users guide Bridge Mode When operating in this mode, one P380 device can connect with another P380 device and form wireless “bridge” interconnecting two or more local networks. Note that all these devices must work in the same frequency channel and must have the same SSID string. Please also note that wireless “bridge” DOES NOT retransmits packets.
P380 Users guide Starting Up To setup P380 for the first time can be performed through a web browser on a computer connected to the local network. The administrator can use one of standard browsers available (e.g., Netscape Navigator, or Microsoft Internet Explorer versions 4.0 or later). Once the setup process is completed, P380 can be managed from any computer on the network that has a web browser. The steps to setup P380 using a web browser are listed below: 1.
P380 Users guide Figure 5: Welcome screen Click on the “Setup Wizard” button on the menu bar to begin P380 device configuration (described in the following section).
P380 Users guide Device Status page Device status page displays all information includes system, interface and network status. Figure 6: Device Status table The Device Status page is divided into to four parts: System Status table - This table shows P380 software version, system uptime (after last reboot), average load, memory usage and radio signal strength (RSSI).
P380 Users guide Network status is shown in the “Network Status ” table - This table shows operating mode of the device, which can be “Router” for AP-Router mode, “AP” – for access point mode and “Bridge” for bridge mode. Network statistics are shown in separate table - This table contains statistics for both interfaces of the P380 – wired and wireless. The wired interface is called LAN, and the wireless interface is called WLAN.
P380 Users guide General Configuration Settings Page Various general device parameters can be set in this page. All of those parameters are optional. Figure 8: General Configuration Settings page These parameters include: Hostname – a general network parameter returned in statistics routines DNS Server address – this Domain Name Server address is assigned to the PCs requesting DNS address through DHCP (Dynamic Host Configuration Protocol).
P380 Users guide Network Configuration Settings page v Router Mode In Router mode, LAN (Local Area Network) and WAN (Wide Area Network – For P380, this can be the enterprise networks on the Internet) configurations can be modified using the LAN Settings and the WAN Settings tables shown as followed: Figure 9: Network Configuration Settings page -1 (Router mode) WAN settings must be set up according to the information provided by the ISP. There is no such restriction on LAN settings.
P380 Users guide i Hint: Use known private IP addresses for the local network, because if you use public addresses, you will not be able to connect to WAN. It is recommended to use IANA (Internet Assigned Numbers Authority) reserved private address space (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16) . v AP Mode In AP and Bridge mode, P380 does not require an active LAN (Local Area Network) interface, so the “LAN Interface Settings” table is not displayed.
P380 Users guide Figure 11: Wireless Configuration Settings page At lease two essential parameters are required to setup : 15
P380 Users guide − Access Point SSID (Service Set Identifier): This is a case-sensitive parameter to uniquely identify your radio network. − Default Channel for BSS: It can be set up by selecting a fixed channel or have the channel automatically assigned. i Hint: Use the site survey utility in System Tools to verify a fixed channel selection. This utility will help the administrator to discover unused channels, or to check the signal strengths of other Access points of the selected channel.
P380 Users guide Figure 12: Waiting and redirection message It indicates that the browser will be redirected to a new site (new IP). If the new site is in a different subnet from the old one (e.g., from 192.168.2.218/24 to 168.20.1.10/24), the redirection function will not work. The IP of the local connected computer must change to the same subnet of the new site (168.20.1.x/24) first.
P380 Users guide Advanced Settings Setting up advanced P380 settings requires some advanced knowledge of the TCP/IP network structure and functionalities. It is recommended that only skilled network administrators should use these settings. Firewall configuration IP firewall configuration page provides user firewall services control. User can add, modify or delete customized firewall rules.
P380 Users guide This page shows service state and firewall rules list. Rules are divided in two parts – Input rules, which apply to the incoming packets, and the Output rules, which apply to the outgoing packets. User can change these rule lists by editing existing rules, deleting unnecessary ones, and adding new rules.
P380 Users guide Destination IP Address – specified the same as Source IP Destination Netmask – specified the same as Source Netmask Destination port(s) – specified the same as Source port Network protocol – network protocol which the rule affects. Can be specified as one of TCP/UDP/ICMP or any i Hint: If an exact port is specified, use of “any” protocol setting makes no sense (different protocols use their own port ranges).
P380 Users guide ACL Configuring All clients MAC are set by acceptable as default in Access Control List function. To deny the MAC address, just click “Add New Rule” button to add the new record. Access Control List setting is shown below: Figure 15: ACL Settings page Static routing configuration Static routing service lets user specify static routes, which is present in system routing table form system startup.
P380 Users guide i Hint: above figure shows default system routes, which are added automatically, and restored after any network configuration. However these routes can be edited for temporary needs. This page provides a user static route list (present on the system), and ability to edit, delete and add routes.
P380 Users guide DHCP Service Configuration The Dynamic Host Configuration Protocol (DHCP) provides IP configuration parameters to hosts in a client-server model. DHCP servers assign network addresses and deliver the configuration parameters to other (client) hosts. DHCP server feature is offered only in AP Router mode. This server set up is done in the DHCP Settings table, which is shown below. Figure 18: DHCP Server Settings page DHCP server service can be enabled or disabled from this page.
P380 Users guide administrator can define local computer, to which data from specified ports of firewall are automatically redirected to ports of this local computer. Port Forwarding Settings page is shown below: Figure 19: Port Forwarding Settings table ~Note: In AP and Bridge mode P380 has no active LAN (Local Area Network) interface, so the “Port Forwarding Settings” page is not displayed From this page, administrator can modify port forwarding rule list by adding new, delete and edit existing rules.
P380 Users guide Figure 20: Port Forwarding Rule editing table As shown in Figure 20, a port forwarding rule consists of protocol specification – UDP or TCP protocol, port on the P380 needed for application, the local IP address and port to which arriving data will be redirected. i Hint: Sometimes games, chat programs and other applications may need to change their network settings to something like “Use Firewall” or “Use proxy” to work properly.
P380 Users guide Figure 21: Administrator Settings table To change the password, you must enter the current password in “Old Password” field, then enter a new password in the “New Password” field. Re-enter the same value in the “Retype New Password” field. Use hard-to-guess password, i.e. more than five characters, containing both letters and numbers, and is not a dictionary word.
P380 Users guide Figure 22: Connected Clients page In the “Client MAC address” column, connected wireless card MAC (hardware) addresses are shown. Signal and Noise columns show radio signal and noise levels. The column, “Rate ”, shows connection bit rate (connection speed) in hundreds of kilobits. This rate can be easily converted in to megabits by dividing this number by 10. For example 110 corresponds to 11Mbits, 55 correspond to 5.5Mbits and so on.
P380 Users guide measured by sending ICMP (Internet diagnostics protocol) stream to the end point device. Data is refreshed every second. To start loopback testing, enter endpoint IP address in the “Endpoint IP address” field and click on the “Start” button in the lower right corner of the page. Status line will show last measured data transfer rate, and the time when this data was received from the endpoint. To stop loopback-testing, click on the “Stop” button.
P380 Users guide Configuring SNMP management SNMP (Simple Network Management Protocol) service is configured in the SNMP Settings page. This page is used for setting up read-only and read-write communities: Figure 24: SNMP Settings Community strings are used for SNMP authentication purposes. It is possible to allow or deny IP address groups from accessing P380 using SNMP. IP address and netmask combination 0.0.0.0/32 means “ANY” IP address. It could be setup by a specified IP, ex 192.168.2.
P380 Users guide Site survey page Figure 25: Site Survey Test Results page Site survey test shows the load situation in the wireless network. Using this test, user can scan for active Access Points; check the operating channels and their respective signal/noise levels. i Hint: Because wireless card is scanning through all radio frequency channels, the page loading time is much longer when compared to the other P380 management pages.
P380 Users guide Figure 26: Monitoring page The Monitoring menu shows TX/RX statistics graph. These statistics show a five-minute average traffic rate over the last 24 hours period. RX (green) indicates incoming (Received) traffic and TX (red) indicates outgoing (Transmitted) traffic. The TX/RX monitoring is restarted on every P380 reboot. The reason is that P380 has no real time clock, and the time used is relative to P380 restart. The first statistics appear as 2 points after 5 minutes after P380.
P380 Users guide Entering this page will put the device into UPGRADE mode. All of the device functions will be SUSPENDED. Once the device enters the UPGRADE mode, it can only be upgraded or rebooted. i Hint: Because upgrade is done using the WEB management screen, all management pages still work, so it is still possible to configure P380 before rebooting it. Figure 27: Upgrade page P380 firmware is upgraded using the “Upgrade” page. In this page, the current firmware version is shown.
P380 Users guide Figure 28: Firmware file selection dialog When firmware file is selected, its name is shown in the “Firmware” field. Then click on the “Upgrade” button to upgrade firmware. A “System Firmware Upgrade Process” screen will be displayed and firmware should be upgraded as shown below: Figure 29: System Firmware Upgrade Process Status A percentage will be showed on the status bar to indicate the upgrade status.
P380 Users guide Upgrade Utility P380 can also be configured as a wireless station, but the unit requires full firmware upgrade, which can not be done in the web site. Therefore the P380 comes with an upgrade utility, “upgrade.exe ”, to allow the user to perform the task. The program runs under MS Windows 2000 family and MS Windows XP. Before the program is executed, the firmware should be located first. It can be found under the root directory in the CD.
P380 Users guide Click on the “Reboot” button to reboot P380 device via web management. All functions will be stopped while the device is rebooted. Reset page To reset the P380 device to the factory setting, click on the “Reset” button. A waiting & redirection message should be shown as below (for the redirection service, please refer to the redirection service section for detail): ~Note: All customized P380 configuration settings will be reset to the default values.
P380 Users guide Hardware Reset To reset the P380 device back to factory settings, except for web management, hardware reset will be another choice. There is no any physical button offered in hardware reset. For convenience sake, P380 offers the hardware reset processes as followed. 1. Unplug the power cable. 2. Re-connect the power cable. 3. Please wait for 5 to 6 seconds. At this moment, please disconnect the power cable. 4. Reconnect the cable on again and device will restart.

P380 Users guide E Ethernet A common, 10Mbps local area network technology invented by Xerox Corporation at the Palo Alto Research Center. Ethernet is a best-effort delivery system that uses CSMA/CD technology. Ethernet can be run over thinwire coaxial cable (10BASE2), thickwire coaxial cable (10BASE5), twisted pair cable (10BASET), or fibre optic cable. F Filter Within the router, a filter is a process used to select which packets will be processed by the router, and which will be ignored or discarded.
P380 Users guide Internet A collection of networks interconnected by a set of routers, which allow them to function as a single, large virtual network. Internet (note the capital “I”) The largest internet in the world consisting of large national backbone networks (such as MILNET, NSFNET, and CREN) and a myriad of regional and local campus networks all over the world. The Internet is a multiprotocol network, but generally carries TCP/IP. Internet address See IP address. Internet Protocol See IP.
P380 Users guide necessary IP address translations. NAT is used for two main tasks – to provide a type of firewall by hiding internal IP addresses and enable a company to use more internal IP addresses. Since they're used internally only, there's no possibility of conflict with IP addresses used by other companies and organizations. Network A computer network is a data communications system which interconnects computer systems at various different sites.
P380 Users guide Route table A table listing information about routes to other hosts or networks, such as the remote network or host address, the interface down which the route exists, the distance to the remote address and the cost of sending data over the route. Router A system responsible for making decisions about which of several paths network (or Internet) traffic will follow.
P380 Users guide Topology A network topology shows the computers and the links between them. A network layer must know the current network topology to be able to route packets to their final destination. U UDP User Datagram Protocol. A transport layer protocol in the TCP/IP suite of protocols.
