2.4.1.1 Address Sharing and Management
The RX3041H Firewall provides NAT to share a single high-speed Internet connection and to save the cost of
multiple connections required for the hosts on the LAN segments connected to the RX3041H. This feature
conceals network address and prevents them from becoming public. It maps unregistered IP addresses of
hosts connected to the LAN with valid ones for Internet access. The RX3041H Firewall also provides reverse
NAT capability, which enables SOHO users to host various servi ces such as e-m ail servers, web servers, et c.
The NAT rules drive the translation mechani sm at the NAT router. T he followin g types of NAT are sup ported
by the RX3041H.
Static NAT – Maps an internal host address to a globally valid Internet address (one-to-one). All
packets are directly translated with t he inf ormation co ntaine d in the map.
Dynamic NAT – Maps an internal host address dynamically to a globally valid Internet address (m-to-
n). The map usually contains a pool of internal IP addresses (m) and a p ool of glo bally valid I nternet I P
addresses (n) with m usually greater than n. Each internal IP address is mapped to one external IP
address on a first come first serve basis.
NAPT (Network Address and Port Translation) – Also called IP Masquerading. Maps many internal
hosts to only one globally v alid Internet addre ss. The m ap usua lly contain s a pool of network p orts to
be used for translation. Every packet is tran slated with the globally val id Internet address; the port
number is translated with a free pool from the pool of net work ports.
Reverse Static – This is inbound mapping that maps a globally valid Internet address to an internal
host address. All packets coming to that external address are relayed to the internal address. This is
useful when hosting services in an internal machin e.
Reverse NAP T – Also called inbo und mapp ing, port mapping, and virt ual serv er. Any packet coming
to the router can be relayed to the internal host based on the protoc ol, port number or IP Addres s
specified in the rule. This is useful when multiple service s are hosted on different int ernal machines.
Note
Appendix A “ALG Configuration” on.
2.4.1.2 ACL (Access Control List)
For a complete listing of all NAT ALGs supported, refer to
ACL rule is one of the basic buil ding blo cks for net work secu rity. Fire wall monito rs each i ndividua l packet,
decodes the header information of inbound and outbound traffic and then either blocks the packet from
passing or allows it to pass based on the contents of the source address, destination address, source port,
destination port, protocol and ot her criteri on, e.g. applicat ion filter, ti me ranges, d efined in t he ACL rules.
ACL is a very appropriate measure for providing isolat ion of one subnet from another. It can be u sed as the
first line of defense in the network to block inbound packets of specific type s from ev er reaching t he prote cted
network.
The RX3041H Firewall’s ACL methodology supports:
Filtering based on destination and source IP address, port number and protocol
Use of the wild card fo r compos ing filter ru les
Filter Rule priorities
Time based filt ers
Applicati on specific filters
User group based f ilters for remote acce ss
2.4.1.3 Stateful Packet Inspection
The RX3041H Firewall uses “stateful packet inspection” that extracts state-related information required for the
security decision from the packet and mainta ins this info rmation for ev aluating subs equent conne ction
attempts. It has awareness of application and creates dynamic sessions that allow dynamic connections so
5
Chapter 2. Getting to Know the RX3041H RX3041H User’s Manual
that no ports need to be opened other than the required ones. This provides a solution which is highly secure
and that offers scalability and extensibility.
2.4.1.4 Defense against DoS Attacks
The RX3041H Firewall has an Attack Defense Engine that protects internal networks from known types of
Internet attacks. It provides automatic prote ction from Denial of Servic e (DoS) attacks such a s SYN flooding,
IP smurfing, LAND, Ping of Death and all re-assembly attacks. It can drop ICMP redirects and IP loose/strict
source routing packets. For example, the RX3041H Firewall provides protection from “WinNuke”, a widely
used program to remotely crash unprotected Windows systems in the Internet. The RX3041H Firewall also
provides protection from a variety of common Internet atta cks su ch a s IP Spoofi ng, Ping of Death, Land Att a ck,
Reassembly and SYN flooding.
The type of attack protections provided by the RX304 1H are listed in Table 2. 3.

2.4.1.5 Application Command Filtering
The RX3041H Firewall allows network administrators to block, monitor, and report on network users access to
non-business and objectionable content. This high-performance content access control results in increased
productivity, lower bandwidth usage and reduced legal liability.
The RX3041H Firewall has the ability to handle active content filtering on certain application protocols such as
HTTP, FTP, SMTP and RPC.
HTTP – You can define HTT P extension based filteri ng schemes for bl ocking
ActiveX
Java Archive
Java Applet s
Microsoft Archives
URLs based on file extensions.
FTP – allows you to def ine and enfo rce the file transf er policy for t he site or group of users
SMTP – allows you to filter operations such as VRFY, EXPN, etc. which reveal excess information
about the recipient.
RPC – allo ws you to filter prog rams based on the assigned RPC p rogram num bers.

RX3041H User’s Manual Chapter 2 Getting to Know the RX3041H
2.4.1.6 Application Level Gateway (ALG)
Applications such as FTP, games etc., open connectio ns dynamically base d on the respective appl ication
parameter. To go through the firewall on the RX3041H, packets pertaining to an application, require a
corresponding allow rule. In the absence of such rules, the packets will be dropped by the RX3041H Firewall.
As it is not feasible to create policies for numerous applications dynamically (at the same time without
compromising security), intelligence in the form of Application Level Gateways (ALG), is built to parse packets
for applications and open dynamic associations. The RX3041H Firewall provides a number of ALGs for
popular applications such as FTP, H.323, RTSP, Microsoft Games, SIP, etc.
2.4.1.7 URL Filtering
A set of keywords that should not appear in the URL (Uniform Resource Locator, e.g. www.yahoo.com) can be
defined. Any URL containing one or more of these keywords will be bl ocked. This is a pol icy independent
feature i.e. it cannot be associated to ACL rules. T his feature can be in dependently enabled or disabl ed, but
works only if firewall is enabled.
2.4.1.8 Log and Alerts
Events in the network, that could be attempts to affect its security, are record ed in the RX3041 H System log
file. Event details are recorded in WELF (WebTrends Enhanced Log Format ) format so that statistical tools
can be used to generate custom reports. The RX3041H Firewall can also forward Syslog information to a
Syslog server on a private network.
The RX3041H Firewall supports:
Alerts sent t o the a dministrat or via e-mai l.
Maintai ns at a minimum, log detai ls such as, time of packet arriv al, description of a ction taken by
Firewall and reason for action.
Supports the UNIX Syslog format.
Sends log report e-mails as scheduled by the network administrator or by default when the log file is
full.
All the messages a re sent in the WELF format.
ICMP logging to sh ow code and type.
2.4.1.9 Remote Access
The RX3041H Firewall allows the network administrator to segregate the user community into Access Policies
per group. A user can log in using the login page (Refer to “User Login Process” on page 67). After a user is
authenticated successfully, the RX3041H Firewall dynamically activates the user-group’s set of access policies.
These policies will subsequently be enforced until the user logs out of the session or until inactivity timeout
period has lapsed.

3.2.6 Assigning static IP addresses to your PCs
In some cases, you may want to assign IP addresses to some or all of your PCs di rectly (often called
“statically”), rather than allowing the RX3041H to assign them. This option may be desirable (but not required)
if:
You have o btained one or mo re public IP addresse s that you want to al ways associat e with specific
computers (for example, if you are using a computer as a public web server).
You maintain different subnets on your LAN.
However, during the first time co nfigurati on of your RX3041H, you must assign an IP address in the
192.168.1.0 network for your PC, say 192.168.1.2, in order to establish connection between the RX3041H and
your PC as the default LAN IP on RX3041H i s pre-confi gured a s 192.16 8.1.1. Ent er 255. 255.25 5.0 for t he
subnet mask and 192.168.1. 1 for the d efault gat eway. T hese setting s may be ch anged lat er to refle ct your true
network environment.
On each PC to which you want to assign static information, follow the instructions on pages 11 through 12
relating only to checking fo r and/or instal ling th e IP protoco l. Once it is i nstall ed, conti nue to foll ow the
instructions for displaying each of the Internet Prot ocol (TCP/IP) properties. Instead of enabling dynamic
assignment of the IP addresse s for the computer, DNS serv er, and default gat eway, cl ick the radio buttons th at
enable you to enter the informatio n manually.
Your PCs must have IP addresses that place them in the same
subnet as the router’s LAN port. If you manually assign IP
Note
addresses to all your LAN PCs, you can fo llow the i nstructi ons in
Chapter 5 to change the router’s LAN port IP address accordingly.
3.3 Part 3 — Quick Configuration of Your Router
In Part 3, you log into the Configuration Manager o n the router and conf igure basic settin gs for your Internet
connection. Your ISP should provide you with the necessary information to complete this step. Note the intent
