4.8.2 ADVANCE: Firewall – Protection Policy Protection Policies defend against common methods of attacking a network and computers within the network. Some of these attacks are classified as a DoS ( Denial of Service ). DoS is an attack in which a network or components of a network are disabled, usually by overloading traffic on the network, in order to prevent authorized and legitimate users to access network resources.
Page 145
Land Attack checking: Land attack is a type of DoS attack that works by sending a spoofed packet containing the same source and destination IP address and port ( The victim’s IP address ). This packet contains a connection request, resulting in a handshake process. At the end of the handshake, the victim sends out an ACK ( ACKnowledge ) request.
Page 146
ICMP Redirection checking: Also known as an ICMP storm attack or smurf attack, ICMP Redirection is another form of DoS. This attack is performed by sending ICMP echo requests to a broadcast network node. The return IP address is spoofed and replaced by the victim’s own address, causing it to send the request back to itself.

Page 156
Note: The Inbound Policy works in a Top-Down fashion according to the Inbound Policy Table. This means that the firewall will apply the policies in order from the top of the table to the bottom. It is critical for both security and user accessibility to the WAN to have inbound policies in the correct order.
Page 157
Dest IP: This specifies the Destination IP for the Inbound Policy. This is the internal ( LAN side, behind the firewall ) IP address or addresses and network that will be affected by the policy. See Src IP above for configuration detail. Src Port: This specifies the Source Port for the Inbound Policy.
Page 158
Deny: Selecting this will cause the policy to deny packet transfer from the Src IP through the Src Port to travel through the Dest Port to the Dest IP. All of these are specified above and must be configured by the user. Time Window Filtering: This field allows you to select a certain time frame from the Time Group in which this policy will be active.
4.8.9 ADVANCE: Firewall – Outbound Policy The Outbound Policy allows you to filter outbound ( From the user side LAN to the WAN ) packets based on a set of rules. This enables you to deny access to different sources and thus increase security. A table of outbound policies is displayed with the following information.

FTP Access from 10.0.0.3~10.0.0.6 through any protocol Converting the access requirements from above so that the Outbound Policy can understand them yields the following: Deny all access from any Src ( LAN ) IP to any Des ( WAN ) IP through any source or...
Appendix A: Network Address Translation Network Address Translation (NAT) translates the IP address a network (LAN) to a different IP address known by another network (WAN). This gives an outside network the ability to distinguish and communicate with a device on the inside network, as the inside network has a private set of IP addresses assigned by the DHCP server, which are not know to the outside network.
A.1 Basic NAT Basic Network Address Translation (NAT) enables outbound sessions for the hosts in a private network to gain 0access the external network. Facts of Basic NAT: Basic NAT allows hosts in a private network to transparently access the external network. Basic NAT maps only one IP addresses in the private domain to each IP address in the public domain.
A.2 Static NAPT NAPT, also known as NAT-PAT, stands for Network Address Translation and Port Address Translation. An extension of Basic NAT, NAPT enables outbound sessions so that the hosts in a private network to access the external network. Facts of NAPT: NAPT multiplexes traffic from the internal network and presents it to the Internet as if it is coming from only one IP address.
A.3 Functional Descriptions This section describes various NAT mechanisms for both outbound and inbound session operations. Together, they provide a mechanism to connect a realm with private addresses to an external realm with globally unique registered addresses. The NAT module allows outbound access with either static or dynamic sessions. Inbound access is normally blocked but selective inbound sessions may be enabled.
A.3.1 Outbound Access The NAT module implements two modes for outbound sessions: NAT mode and NAPT mode. □ NAT Mode: NAT mode implements the Basic NAT functionality. 1. Static session mapping is required for any local host to access the public domain. 2.
Page 173
inactivity timer expires. Thus, changes to the Route Table may not change the NAT packet forwarding on existing sessions. This may create confusion in some cases. For example, there are two WAN connections: WAN1 is the default route and goes to internet, WAN2 has an internal server behind it and a manual route entry is entered to reach that internal server.
A.3.2 Inbound Access Inbound access is normally blocked; however, selective inbound sessions may be enabled. The NAT module implements two types of inbound access control: Virtual Server and Demilitarized Zone (DMZ). □ Virtual Server: The term "Virtual Server" came from the concept of subdividing one physical system into multiple "virtual"...
Page 175
4. One popular use of this feature is when inbound connections to a range of ports are required and it is impractical or impossible to accommodate them via port mappings. 5. The DMZ opens all ports on this particular local host to all unsolicited traffic, therefore posing some security risk.
A.3.3 Application Layer Gateways (ALGs) Application Layer Gateways (ALG) may also be referred to as Application Specific Gateway or Application Level Gateway. Although the address translation itself is application independent, it does create complications. Some protocols such as FTP, DNS, and SIP require payload monitoring and alteration to traverse through NAT. ALGs are needed to accompany NAT to perform these complicate tasks.
