Chapter 15 The Firewall Screens MAX-207HW2R User’s Guide 151 15.4 Technical Reference The following section contains additional technical information about the MAX- 207HW2R features described in this chapter. 15.4.1 Stateful Inspection Firewall. Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises. 15.4.2 Guidelines For Enhancing Security With Your Firewall 1Change the default password via web configurator. 2Think about access control before you connect to the network in any way. 3Limit who can access your router. 4Don't enable any local service (such as telnet or FTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. 6Protect against IP spoofing by making sure the firewall is active. 7Keep the firewall in a secured (locked) room. 15.4.3 The “Triangle Route” Problem A traffic route is a path for sending or receiving data packets between two Ethernet devices. You may have more than one connection to the Internet (through one or more ISPs). If an alternate gateway is on the LAN (and its IP address is in the same subnet as the MAX-207HW2R’s LAN IP address), the Chapter 15 The Firewall Screens MAX-207HW2R User’s Guide 152 “triangle route” (also called asymmetrical route) problem may occur. The steps below describe the “triangle route” problem. 1A computer on the LAN initiates a connection by sending out a SYN packet to a receiving server on the WAN. 2The MAX-207HW2R reroutes the SYN packet through Gateway A on the LAN to the WAN. 3The reply from the WAN goes directly to the computer on the LAN without going through the MAX-207HW2R. As a result, the MAX-207HW2R resets the connection, as the connection has not been acknowledged. Figure 68 “Triangle Route” Problem 15.4.3.1 Solving the “Triangle Route” Problem If you have the MAX-207HW2R allow triangle route sessions, traffic from the WAN can go directly to a LAN computer without passing through the MAX-207HW2R and its firewall protection. Another solution is to use IP alias. IP alias allows you to partition your network into logical sections over the same Ethernet interface. Your MAX-207HW2R supports up to three logical LAN interfaces with the MAX-207HW2R being the gateway for each logical network. It’s like having multiple LAN networks that actually use the same physical cables and ports. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the MAX-207HW2R to your LAN. The following steps describe such a scenario. 1A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN. 2The MAX-207HW2R reroutes the packet to Gateway A, which is in Subnet 2. Chapter 15 The Firewall Screens MAX-207HW2R User’s Guide 153 3The reply from the WAN goes to the MAX-207HW2R. 4The MAX-207HW2R then sends it to the computer on the LAN in Subnet 1. Figure 69 IP Alias Chapter 15 The Firewall Screens MAX-207HW2R User’s Guide 154 MAX-207HW2R User’s Guide 155 CHAPTER 16 Content Filter 16.1 Overview Use the TOOLS > Content Filter screens to create and enforce policies that restrict access to the Internet based on content Internet content filtering allows you to create and enforce Internet access policies tailored to their needs. Content filtering is the ability to block certain web features or specific URL keywords. The MAX-207HW2R can block web features such as ActiveX controls, Java applets, cookies and disable web proxies. The MAX- 207HW2R also allows you to define time periods and days during which the MAX- 207HW2R performs content filtering. 16.1.1 What You Can Do in This Chapter •The General screen (Section 16.2 on page 156) lets you set up a trusted IP address, which web features are restricted, and which keywords are blocked when content filtering is effective. •The Schedule screen (Section 16.3 on page 158) lets you schedule content filtering.

Ltd., Taoyuan Branch LAB LOCATION: No. 81-1, Lu Liao Keng, 9th Ling,Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien 307, Taiwan Report No.: SA990415E05 Report Format Version 3.0.1 2 RF Exposure Measurement 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in our lab, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500 ... ... F/300 6 1500-100,000 ... ... 5 6 (B)Limits For General Population / Uncontrolled Exposure 300-1500 ... ... F/1500 30 1500-100,000 ... ... 1.0 30 F = Frequency in MHz Report No.: SA990415E05 Report Format Version 3.0.1 3 3. FRIIS FORMULA Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 20cm. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT OPERATING CONDITION The software provided by client enabled the EUT to transmit and receive data at specific channel frequencies individually. 5. CLASSIFICATION The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Temporary Fixed Device Report No.: SA990415E05 Report Format Version 3.0.1 4 6.

This confirmed that the device comply with FCC 1.1310 MPE limit. --- END ---
