    H A P T E R 19.1 Overview A virtual private network (VPN) provides secure communications between sites without the expense of leased site-to-site lines. A secure VPN is a combination of tunneling, encryption, authentication, access control and auditing. It is used to transport traffic over the Internet or any insecure network that uses TCP/IP for communication.

    Chapter 22 Network Address Translation (NAT) What NAT Does In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host.

    H A P T E R 30.1 Overview This chapter covers how to use the ZyWALL’s ALG feature to allow certain applications to pass through the ZyWALL. An Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the application layer.
  • Page 532 Chapter 30 ALG Screen ALG and the Firewall The ZyWALL uses the dynamic port that the session uses for data transfer in creating an implicit temporary firewall rule for the session’s traffic. The firewall rule only allows the session’s traffic to go through in the direction that the ZyWALL determines from its inspection of the data payload of the application’s packets.
  • Page 533: Figure 317 H.323 Alg Example

    • You must configure the firewall and port forwarding to allow incoming (peer-to-peer) calls from the WAN to a private IP address on the LAN, DMZ or WLAN. The following example shows H.323 signaling (1) and audio (2) sessions between H.323 devices A and Figure 317 H.323 ALG Example •...

  • Page 535: The Alg Screen

    Figure 320 SIP ALG Example SIP Signaling Session Timeout Most SIP clients have an “expire” mechanism indicating the lifetime of signaling sessions. The SIP user agent sends registration packets to the SIP server periodically and keeps the session alive in the ZyWALL. If the SIP client does not have this mechanism and makes no calls during the ZyWALL SIP timeout default (60 minutes), the ZyWALL SIP ALG drops any incoming calls after the timeout period.

  • Page 695: Filter Configuration

    H A P T E R This chapter shows you how to create and apply filters. 46.1 Introduction to Filters Your ZyWALL uses filters to decide whether to allow passage of a data packet and/or to make a call. There are two types of filter applications: data filtering and call filtering. Filters are subdivided into device and protocol filters, which are discussed later.
  • Page 696: The Filter Structure Of The Zywall

    Chapter 46 Filter Configuration 46.1.1 The Filter Structure of the ZyWALL A filter set consists of one or more filter rules. Usually, you would group related rules, e.g., all the rules for NetBIOS, into a single set and give it a descriptive name. The ZyWALL allows you to configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system.
  • Page 697: Figure 437 Filter Rule Process

    Chapter 46 Filter Configuration Figure 437 Filter Rule Process You can apply up to four filter sets to a particular port to block multiple types of packets. With each filter set having up to six rules, you can have a maximum of 24 rules active for a single port.

    P P E N D I X Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
  • Page 788: Figure 500 Basic Service Set

    Appendix C Wireless LANs Figure 500 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.
  • Page 789: Figure 501 Infrastructure Wlan

    Figure 501 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from an adjacent AP (access point) to reduce interference.
  • Page 790: Figure 502 Rts/Cts

    Appendix C Wireless LANs Figure 502 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
  • Page 791: Table 284 Ieee 802.11G

    If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type Preamble is used to signal that data is coming to the receiver.
  • Page 792: Table 285 Wireless Security Levels

    Appendix C Wireless LANs Wireless security methods available on the ZyWALL are data encryption, wireless client authentication, restricting access by device MAC address and hiding the ZyWALL identity. The following figure shows the relative effectiveness of these wireless security methods available on your ZyWALL.
  • Page 793: Types Of Eap Authentication

    Determines the network services available to authenticated users once they are connected to the network. • Accounting Keeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server.
  • Page 794 Appendix C Wireless LANs For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.
  • Page 795: Table 286 Comparison Of Eap Authentication Types

    Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen.
  • Page 796 Appendix C Wireless LANs Encryption Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.
  • Page 797: Figure 503 Wpa(2) With Radius Application Example

    Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built- in "Zero Configuration"...
  • Page 798: Figure 504 Wpa(2)-Psk Authentication

    Appendix C Wireless LANs 3 The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys.
  • Page 799: Antenna Characteristics

    Antenna Overview An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN.
  • Page 800: Positioning Antennas

    Appendix C Wireless LANs Positioning Antennas In general, antennas should be mounted as high as practically possible and free of obstructions. In point-to–point application, position both antennas at the same height and in a direct line of sight to each other to attain the best performance. For omni-directional antennas mounted on a table, desk, and so on, point the antenna up.
