and TV
Radio
The Model 3201 or 3241 generates and uses radio frequency energy, and if not installed and used properlythat is, in strict accordance with the manufacturer’s instructions-may cause interference to radio and television
reception. The Models 3201 and 3241 have been tested and found to comply with the limits for a Class A
computing device in accordance with specifications in Subpart B of Part 15 of FCC rules, which are designed
to provide reasonable protection from such interference in a commercial installation. However, there is no
guarantee that interference will not occur in a particular installation. If the Model 3201 or 3241 does cause
interference to radio or television reception, which can be determined by disconnecting the unit, the user is
encouraged to try to correct the interference by one or more of the following measures: moving the computing
equipment away from the receiver, re-orienting the receiving antenna and/or plugging the receiving equipment
into a different AC outlet (such that the computing equipment and receiver are on different branches).
CE Notice
The CE symbol on your Patton Electronics equipment indicates that it is in compliance with the Electromagnetic Compatibility (EMC) directive and the Low Voltage Directive (LVD) of the European Union (EU). A

• When in the default out position, the Ethernet circuitry takes on a straight-through MDI configuration and
functions as a transceiver. It will connect directly to a hub.
• When in the in position, the Ethernet circuitry is configured in cross-over MDI-X mode so that a straight-

Product Overview
The Model 3201 modem operates as a bridge or a router and has two ports for communication:
• The Ethernet port—Connects to the LAN side of the connection
• The Line port—Provides the G.SHDSL transmission connection between the CPE and CO DSL modem
The modem provides all layer 2 and layer 3 protocols required for end-to-end-link communication.
When configuring the 3201, questions must be answered so the 3201 functions as desired. For example, when
a router or bridge module needs to be activated, some questions would be:
• Is a default gateway required?
• Which encapsulation technique is best for this application: PPPoA, Frame Relay, PPPoE or another?
These decisions can be made and implemented more easily if the Model 3201’s fundamental architecture is
understood. Also, while configuring the Model 3201 via a browser using the built-in HTTP server is very intuitive, an understanding of the architecture is essential when using the command-line interface (CLI) commands.
The fundamental building blocks comprise a router or bridge, interfaces, and transports. The router and bridge
each have interfaces. A transport provides the path between an interface and an external connection. For example, the Ethernet transport attaches to an Internet Protocol (IP) interface. A transport consists of layer 2 and
everything below it. Creating a transport and attaching it to a bridge or router’s interface enables data to be
bridged or routed. The supported transports are PPPoA, PPPoE, Frame Relay, RFC 1483 (Multiprotocol
Encapsulation over ATM AAL5), IPoA, PPPoH, and Ethernet.
Configuring an interface and transport for the router or bridge requires naming the interface and transport before
attaching them. When using the built-in HTTP server web browser, this is done automatically. But when configuring the Model 3201 via CLI commands through the RS-232 control port, it must be done manually.
Model 3201 modems can connect over an ATM PVC or HDLC transport.
The PVC requires the configuration of the virtual path identifier (VPI) and virtual circuit identifier (VCI). The
VPI can be any integer between 0–4095 inclusive. The general rule for the VCI is an integer between 1–65,535
inclusive. Examples in this manual use a VCI of 600 or above. The main restriction in choosing a VCI is that
VCIs below 32 are reserved for such predefined functions as ILMI. The VCI values of 600 and above used in
this manual are also above the range used by many signaling implementations for SVCs.
The HDLC is a packet-based transmission across the DSL Link.
Several ATM connections are offered to address a variety of user applications. Although they all use RFC1483
as the transport mechanism between the two 3201 modems, WAN services may use different PPP applications,
such as PPPoE routed, PPPoA routed, or PPPoA bridged. Each one has its advantages and disadvantages.
Applications Overview
The Model 3201 is used for bridged or routed applications.
Note In bridged applications the 3201 modem functions transparently on layer 2 to
provide MAC level bridging for Ethernet networks. The bridging is between
Ethernet and the DSL link between the two 3201 modems. The devices
attached to each 3201 are on the same subnet. The number of attached devices
and the size of the filter table are configurable. No IP address is necessary unless
18 Product Overview
Model 3201 G.SHDSL Integrated Access Device User Guide 2 • Product Overview
the administrator desires management through a web browser. Then an IP
address is necessary for the administrator to access the 3201 modem.
In a typical bridged configuration, the DSL bridge is transparent to the network. It bridges the DSL line to
the Ethernet line, making both sides appear as a single subnet. However, it may still be beneficial to provide an
IP address to the DSL modem for management. In the bridged configuration it is not necessary for the Ethernet port to have an IP address.

In a typical routed configuration, the DSL router is treated as a separate device on the network that receives
packets from the PC and DSLAM. The Ethernet and DSL networks are configured as separate IP subnets. The
PC must have the DSL router set up as its default gateway.

Model 3201 applications are divided as follows:
• Connecting two stand-alone Model 3201 Bridge/Routers back-to-back using PPPoH Bridged or PPPoH
Routed. PPPoH Bridged can be considered as Ethernet extension since the same logical LAN exists at both
ends of the 3201s and only bridging is required. PPPoH is network extension in the more general sense
since a different logical network is on each end of the 3201s.
• Connecting the Model 3201 bridge/routers as a CPE device to a DSLAM. They can be configured for
bridged or routed mode.
– The bridged modes commonly used to connect to a DSLAM are RFC1483, HDLC (PPPoH), and
PPPoA.
– The routed modes are RFC1483, HDLC (PPPoH), PPPoA, IPoA and PPPoE.
For more information about router modem applications, refer to Chapter 4, “Basic Application Configurations” on page 27 and Chapter 5, “Specialized Configurations” on page 79.

Introduction
The basic applications are divided according to whether the application is bridged or routed.
The bridged applications are RFC 1483 Bridged, PPPoA Bridged, and HDLC Bridged.
The routed applications are RFC 1483, PPPoA, IPoA, PPPoE, and HDLC.
Another way of organizing the applications is according to the type of encapsulation: PPP, RFC 1483, or Frame
Relay. PPP encapsulation is available as PPPoA bridged or routed and PPPoE. RFC 1483 and Frame Relay can
be configured for bridged and routed connections.
The following table shows the parameters that can be configured via the HTTP server using a web browser.

RFC 1483 Bridged Configuration.
No additional IP addresses are needed other than the IP address chosen earlier. In fact, if you are configuring and
managing the model 3201 only from the CLI (Command Line Interface), an IP address is not needed at all. The
limitation of no IP address precludes the user from doing web management of the 3201 since management is
done via the Ethernet port.
As in the PPPoA Bridged application, both sides of the RFC 1483 bridged connection are on the same subnet.

Five routed WAN services are offered, RFC 1483, PPPoH, IPoA, PPPoA, and PPPoE Routed.
RFC 1483 Routed
RFC 1483 provides the simplest method of connecting end stations over an ATM network. User data in the
form of Ethernet packets is encapsulated into AAL-5 PDUs for transport over ATM. RFC 1483 provides no
authentication and configuration that would be provided by PPP.

PPPoA Routed (RFC 2364)
This routed application is very similar to the PPPoA Bridged application. The user data for transmission is in
the form of IP packets but encapsulated in a PPP packet, transmitted and received through a PPP session to the
connection. The PPP packets are encapsulated according to RFC 2364 for transmission over the ATM link.
The packets are de-encapsulated on the receive side so that the IP data can be delivered to the end user.
The Central (Model 3201) end functions as a local ISP which will authenticate the Remote user (Model
3201). The CPE side, with Remote and 3201-A, may represent a home PC which is connecting to a centralized PPP server (Local and 3201—B).
Since this is a routed application, there are differences to be noted. Referring to the application diagram, three
unique subnets exist. The Ethernet LAN on the 3201 and Remote side, the Ethernet LAN on the 3201 and
Central side, and lastly, the subnet of the ATM’s PVC link between the two modems, 3201-A and 3201-B.
The 3201-B and Local end (the Central side) may also be a DSLAM.

IPoA Routed (RFC 1577)
User data in the form of IP packets is encapsulated into AAL-5 PDUs for transport over ATM. The fact that
the user data is routed at an IP layer instead of bridged at a MAC layer allows the source and destination to be
on different subnets. A notable drawback of IPoA is the lack of authentication and configuration that would be
provided by PPP.

Introduction
Security provides the ability to setup and enforce security policies. The policies define the types of traffic permitted to pass through a gateway, either inbound, outbound, or both, and from which origins the traffic may
be allowed to enter.
Within the security configuration is a stateful firewall. A stateful firewall utilizes a security mechanism to maintain information concerning the packets it receives. This information is used for deciding dynamically whether
or not a packet may pass through.
Port filters are rules that determine how a packet should be handled. The rules define the protocol type, the
range of source and destination port numbers and an indication whether the packet is allowed or not.
Security triggers are used with applications that require and create separate sessions. The most common example is FTP. An FTP client establishes a connection to a server using port 21, but data transfers are done on a
separate connection or port. The port number, and who makes the connection, can vary depending on the
FTP client. To allow FTP to work without triggers, you would need to set up port filters allowing the correct
port numbers through. This is a significant security risk.
This risk can be avoided by using security triggers. Triggers tell the security mechanism to expect these secondary sessions and how to handle them. Rather than allowing a range of port numbers, triggers handle the situation dynamically, opening the secondary sessions only when appropriate. The triggers work without needing to
understand the application protocol or reading the payload of the packet, although this does happen when
using NAT.
Triggering allows you to set up a trigger for different application protocols that use multiple sessions. The timeout between sessions and whether or not session chaining are allowed are configurable. Session chaining is not
needed for FTP but is for NetMeeting.
See Chapter 7, “NAT (Network Address Translation)” on page 95.
Configuring the router
The configuration of security assumes that the 3201/Router modem already has a valid IP address for the
Ethernet port so that the user may access the modem via the web page. If the IP address is still the factory
default, go to the section in Chapter 3 entitled IP Address Quick Start Modification.
In this example the WAN transport between the two 3201/Router modems will be IPoA.
1. Click on WAN Connections under Configuration on the 3201’s Menu.
2. Click on Create a New Service.
3. Select IPoA Routed and click on the Configure button.
4. For this example, enter IPoA Security Firewall in the Description field.
5. VPI remains at 0. Change VCI to be 100.
6. Click on WAN IP address and enter 192.168.101.1 in the adjacent box. The default IP mask is
255.255.255.0.
7. Click on Apply.
86 Introduction
Model 3201 G.SHDSL Integrated Access Device User Guide 6 • Security
The next step in configuring the router is adding the default gateway route. Since the WAN IP address of the
3201 modem at the CO site is 192.168.101.2, this will be the gateway for the 3201 modem at the CPE site,
the modem we are currently configuring.
1. Click on IP Routes under Configuration on the 3201 modem’s Menu.
2. Click on Create a New IP Route.
3. Enter 192.168.101.2 in the box adjacent to Gateway.
4. Leave Destination and Netmask both as 0.0.0.0 because this is the gateway default route.
5. Click on Create and the route will be entered.
6. The default gateway can be verified by clicking on IP Routes under Status in the menu.
Configuring the security interfaces
The interfaces and routes have been configured on the 3201 Router modem which will function as the firewall.
The Ethernet side of the 3201 will be configured to be an internal security interface whereas the WAN side is
configured as an external security interface since it is on “public” side of the modem connection.
1. Click on Security under Configuration on the 3201 modem’s menu.
2. Under Security Interfaces, click on Add Interface.
3. Select Name of the WAN port (ipoa-0) and Interface Type to be external. Click on Apply.
Configuring the security interfaces 87
6 • Security Model 3201 G.SHDSL Integrated Access Device User Guide
4. Add one more security interface by repeating step 2.
5. Select Name of the LAN port (ip1) and Interface Type to be internal. Click on Apply.
Now the Firewall policies will be added between the security interfaces. Only one Firewall policy, called etoi, is
added between the external and internal interfaces.
1. Under Policies, Triggers and Intrusion Devices on the Security page, click on Firewall Policy
Configuration.
2. In the Current Firewall Policies page, click on New Policy.
3. Select the parameters so the policy applies between interface of types: external
internal.
Also Validators will block traffic. This blocks all hosts.
4. Click on Apply.
Deleting a Firewall Policy
To delete a Firewall Policy, follow these Command Line Interface (CLI) commands via the Console port.
→

------------------------------------------------------------------ 1 | item0 | external | internal | false
-------------------------------------------------------------------
→
firewall delete policy item0
The firewall policy named item0 is now deleted.
Enabling the Firewall
At this point, both security and the firewall can be enabled and the network is secure. All the interfaces which
have been defined are protected: all traffic blocked between the internal and external interfaces.
1. Return to the Security page.
2. Under Security State select Enabled for Security and click on Change State.
3. Then select Enabled for the Firewall and click on Change State.
The network is now secure. All the interfaces which have been defined are protected and all traffic is blocked
between different the different interface types. That is, all traffic is blocked between the external and internal
interfaces.
The next section describes how to configure the Firewall for allowing certain types of data transfer to occur
between the PC’s on different networks.
Firewall Portfilters
Next, we configure the Firewall to permit certain types of data transfer between the PCs on the different networks. This is done by the implementation of Firewall portfilters. Portfilters are individual rules that determine
what kind of traffic can pass between two interface types.
For the Transport Type below, the different types are:
Transport Type Abbreviation
1 ICMP
2 IGMP
3 GGP
4 IP
6 TCP
8 EGP
9 IGP
17 UDP
46 RSVP
47 GRE
89 OSPFIGP
92 MTP
Enabling the Firewall 89
6 • Security Model 3201 G.SHDSL Integrated Access Device User Guide
Transport Type Abbreviation
94 IPIP
To allow pings between the two PCs:
1. From the Configuration Menu, > Configuration > Security > Firewall Policy Configuration > Port Filters >
Add Raw IP Filter
2. Enter 1 (for ICMP) in Transport Type.
3. Both Inbound and Outbound should be allowed.
4. Click on Apply.
You can now ping between the two networks
Security Triggers
Security triggers are used to allow an application to open a secondary port in order to transport data. The most
common example is FTP. This procedure is to set up a trigger on the Firewall to have an FTP session from PC
A to PC B, but not the reverse.
1. First, create an outbound-only portfilter for FTP and add it to the item0 policy.
2. Following the path given in step 1 for the ping portfilter, click on Add TCP Filter.
3. The Port Range is entered as 21 for both Start and End.
4. Set Inbound as Block, but Outbound as Allow.
5. Click on Apply.
90 Security Triggers
Model 3201 G.SHDSL Integrated Access Device User Guide 6 • Security
After configuring the FTP portfilter, you can open an ftp session from Remote to Local, however you can issue
ftp commands (e.g., login, cd, etc.) but transfer data (e.g., ls, dir, get, put commands). The portfilter allows an
ftp control channel but does not allow the use of a secondary data channel for passing data by ftp.
To enable the ftp data channel, add a trigger which will open a secondary channel only when data is being
passed. This prevents the need to open too many ports which offer a security risk.
1. From the Configuration Menu, > Configuration > Security > Firewall Trigger Configuration > New Trig-
ger.
2. Set the parameters as follows:
– Transport Type = tcp
– Port Number Start = 21
– Port Number End = 21
– Allow Multiple Hosts = Block
– Max Activity Interval = 3000
– Enable Session Chaining = Block
– Enable UDP Session Chaining = Block
– Binary Address Replacement = Block
– Address Translation Type = none
3. Click on Apply.
You should now be able to use ftp commands to pass data between Remote and Local.
Intrusion Detection System (IDS)
The security feature in the 3201 Router modem provides protection from a number of attacks. Some attacks
cause a host to be blacklisted (i.e., no traffic from that host is accepted under any circumstances) for a period of
time. Other attacks are simply logged. The subsequent table is a summary of the attacks detected.

1. To enable IDS, click on Enabled for “Intrusion Detection Enabled” on the “Security Interface Configura-
tion” page. Then click on Change State(s).
2. Click on Configure Intrusion Detection.
3. You may choose which of the parameters to configure and for which value.
– Use Blacklist:Default = 10 minutes when enabled.
If IDS has detected an intrusion an external host, access to the network is denied for ten minutes.
– Use Victim Protection:Default = Disabled.
Enables Victim Protection. Victim Protection protects the victim from an attempted spoofing attack.
Web spoofing allows an attacker to create a ‘shadow’ copy of the world wide web (WWW). All access to
the shadow Web goes through the attacker’s machine, so the attacker can monitor all of the victim’s
activities and send false data to or from the victim’s machine. When enabled, packets destined for the
victim host of a spooking style attack are blocked.
– DOS Attack Block Duration:Default = 1800 seconds (30 minutes).
A Denial of Service (DOS) attack is an attempt by an attacker to prevent legitimate users from using a
service. If a DOS attack is detected, all suspicious hosts are blocked by the firewall for a set time limit
– Scan Attack Block Duration:Default = 86400 seconds
Sets the duration for blocking all suspicious hosts. The firewall detects when the system is being scanned
by a suspicious host attempting to identify any open ports.
– Victim Protection Block Duration:Default = 600 seconds (10 minutes).
Sets the duration of the block in seconds.
– Maximum TCP Open Handshaking Count:Default = 100
Sets the maximum number of unfinished TCP handshaking sessions per second that are allowed by a
92 Intrusion Detection System (IDS)
Model 3201 G.SHDSL Integrated Access Device User Guide 6 • Security
firewall before a SYN Flood is detected. SYN Flood is a DOS attack. When establishing normal TCP
connections, three packets are exchanged: (1) A SYN (synchronize) packet is sent from the host to the
network server. (2) A SYN/ACK packet is sent from the network server to the host. (3) An Ack
(acknowledge) packet is sent from the host to the network server. If the host sends unreachable source
addresses in the SYN packet, the server sends the SYN/ACK packets to the unreachable addresses and
keeps resending them. This creates a backlog queue of unacknowledged SYN/ACK packets. Once the
queue is full, the system will ignore all incoming SYN request and no legitimate TCP connections can
be established.
– Once the maximum number of unfinished TCP handshaking sessions is reached, an attempted DOS
attack is detected. The firewall blocks the suspected attacker for the time limit specified in the DOS
Attack Block Duration parameter.
– Maximum Ping Count:Default = 15
Sets the maximum number of pings per second that are allowed by the firewall before an Echo Storm is
detected. Echo Storm is a DOS attack. An attacker sends oversized ICMP datagrams to the system using
the ‘ping’ command. This can cause the system to crash, freeze, or reboot, resulting in denial of service
to legitimate users.
– Maximum ICMP Count:Default = 100
Sets the maximum number of ICMP packets per second that are allowed by the firewall before an ICMP
Flood is detected. An ICMP Flood is a DOS attack. The attacker tries to flood the network with ICMP
packets in order to prevent transmission of legitimate network traffic.
