3.3.7 SERVICES
3.3.7.1 PORT FORWARDING (VIRTUAL SERVER)
Port forwarding allows to direct incoming traffic from the WAN side to a specific IP address on the LAN
side. i.e. create a port forwarding rule to make a computer on the LAN, such as a Web or FTP server,
available to Internet users without having to obtain a public IP address for that computer. The computer’s
private IP address is translated to the public IP address in all incoming and outgoing data packets.
• Go to “NAT” option , select the “NAT Rule entry” option , click on “Add”
• Under “NAT Rule Entry” , select the Rule flavour as “Port forwarding”
CHAPTER-3
D-Link GLB-802C ADSL2+ Router User Manual 21
• Enter a “Rule id “.The Rule ID determines the order in which rules are invoked (the lowest numbered
rule is invoked first, and so on). To define two or more rules that act on the same set of IP
addresses, be sure to assign the Rule ID so that the higher priority rules are invoked first. It is
recommended to specify rule IDs as multiples of 5 or 10 so that, in the future, Inserting a rule
between two existing rules is possible. When a data packet matches a rule, the data is acted upon
according to that rule and is not subjected to higher-numbered rules.
• From the IFName drop-down list, select the interface on the device to which this rule applies.
Typically, NAT rules are used for communication between the LAN and the Internet. Because the
device uses the WAN interface (which is ppp-0 or eoa-0) to connect the LAN to the ISP, it is the
usual IFName selection.
• In the Local Address From field and Local Address To fields, type the starting and ending IP
addresses, respectively, of the range of private address used on the network that is to be translated.
• In the Global Address From and Global Address To fields, type the public IP address assigned by
the ISP. In case of dynamic global address leave the global address field blank. (i.e. 0.0.0.0) .Enter
the appropriate port settings.
• Click Submit a page displays to confirm the change, click close to return to the NAT
Configuration page. The new rule should display in the NAT Rule Configuration table.
3.3.7 .2 RIP
RIP is an Internet protocol to share routing table information with other routing devices on the LAN,
at the ISP’s location, or on remote networks connected via the ADSL line.
CHAPTER-3
D-Link GLB-802C ADSL2+ Router User Manual 22
3.3.7.3 IP FILTERING
The IP filter feature enables to create rules that control the forwarding of incoming and outgoing data
between the LAN and the Internet and within the LAN. It is possible to create IP filter rules to block
attempts by certain computers on the LAN to access certain types of data or Internet locations and also
block incoming access to computers on the LAN.
When an IP filter rule is defined and the feature is enabled, router examines data packets to determine
whether they meet criteria set forth in the rule. The criteria can include the network or internet protocol
the packet carries, the direction in which it is traveling (for example, from the LAN to the Internet or vice
versa), the IP address of the sending computer, the destination IP address, and other characteristics of the
packet data.
If the packet matches the criteria established in a rule, the packet can either be accepted (forwarded
towards its destination), or denied (discarded), depending on the action specified in the rule.
a. Configuring IP Filter Global Settings
The IP Filter Configuration page enables to configure the following global IP filter settings.
• Security Level: This setting determines which IP filter rules take effect, based on the security level
specified in each rule. For example, when High is selected, only those rules that are assigned a
security value of High will be in effect. The same is true for the Medium and Low settings. When
“None” is selected, IP filtering is disabled.
CHAPTER-3
D-Link GLB-802C ADSL2+ Router User Manual 23
• Private/Public/DMZ Default Action: This setting specifies a default action to be taken (Accept or
Deny) on private, public interfaces when they receive packets that do not match any of the filtering
rules.
• A public interface typically connects to the Internet. PPP, EoA, and IPoA interfaces are typically
public. Packets received on a public interface are subject to the most restrictive set of firewall
protections defined in the software. Typically, the global setting for public interfaces is Deny, so
that all accesses to the LAN initiated from external computers are denied (discarded at the public
interface), except for those allowed by a specific IP filter rule.
• A private interface connects to the LAN, such as the Ethernet interface. Packets received on a
private interface are subject to a less restrictive set of protections, because they originate within
the network. Typically, the global setting for private interfaces is Accept, so that LAN computers
have access to the ADSL/Ethernet routers' Internet connection.
b. Creating IP Filter Rules
To create an IP filter rule, various criteria are set that must be met in order for the rule to be invoked.
Use these instructions to add a new IP filter rule.
• On the IP Filter Configuration page, click Add.
CHAPTER-3
D-Link GLB-802C ADSL2+ Router User Manual 24
Enter or select data for each field that applies to the rule. The following table describes the fields:
Field Description
Rule ID
Each rule must be assigned a sequential ID
number. Rules are processed from lowest to
highest on each data packet, unti l a match i s
found. It is recommended to assign rule IDs in
multiples of 5 or 10 (e.g., 10, 20, 30) so that
enough room is left between them for inserting
new rules if necessary.
Action
The action that will be taken when a packet
matches the rule criteria. The action can be Accept
(forward to destination) or Deny (discard the
packet).
Direction
Specifies whether the rule should apply to data
packets that are incoming or outgoing on the
selected interface.
Incoming refers to packets coming from the LAN,
and outgoing refers to packets going to the
Internet.
Interface
The interface on the router on which the rule will
take effect.
In Interface
The interface from which packets must have been
forwarded to the interface specified in the
previous selection. This option is va lid o nly for
the outgoing direction.
Log Option
When Enabled is selected, a log entry will be
created on the system each time this rule is
invoked. The log entry will incl ude the time of the
violation, the source address of the computer
responsible for the violation, t he destinati on IP
address, the protocol being used, the source and
destination ports, and the number viola tions
occurring in the previous x minutes.
Security Level
The security level that must be ena bled globa lly
for this rule to take affect. A rule will be active
only if its security level is the same as the globally
configured setting. For example, if the rule is set
to Medium and the global firewall level is set to
Medium, then the rule will be active; but if the
global firewall level is set to High or Low, the n
the rule will be inactive.
Black List Status
Specifies whether or not a violatio n of t his rule
will result in the offending computer's IP
address being added to the blacklist, which blocks
the router from forwarding packets from that
source for a specified period of time.
Log Tag
A description of up to 16 characters to be
recorded in the log in the event that a packet
violates this rule. Be sure to set the Log O ption to
Enable when a Log Tag is configured.
CHAPTER-3
D-Link GLB-802C ADSL2+ Router User Manual 25
Field Description
Start/End Time
The time range during which this rule is to be in
effect, specified in military units.
Src IP Address/Dest IP Address
IP address criteria for the source computer(s)
(from which the packet originates) and the
destination computer. In the drop-down list, it is
possible to configure the rule to be invoked on
packets containing:
any: any source IP address.
lt: any source IP address that is numerically less
than the specified address.
lteq: any source IP address that is numerically
less than or equal to the specified address.
gt: any source IP address that is numerically
greater than the specified address.
eq: any source IP address that is numerically
equal to the specified address.
neq: any source IP address that is not equal to the
specified address.
range: any source IP address that is within the
specified range, including its endpoints.
out of range: any source IP address that is outside
the specified range.
self: the IP address of the ADSL/Ethernet router
interface on which this rule takes effect.
bcast: (destination address only) Specifies that
the rule will be invoked for any packets sent to the
broadcast address for the receiving interface. (The
broadcast address is used to send packets to all
hosts on the LAN or subnet connected to the
specified interface.) When this option is selected,
address need not be specified, so the address
fields are dimmed.
Protocol
The basic IP protocol criteria that must be met for
rule to be invoked. Using the options in the
drop-down list, specify that packe ts must contain
the selected protocol (eq), that they must not
contain the specified protocol (neq), or that the
rule can be invoked regardless of the protocol
(any). TCP, UDP, and ICMP are comm on IP
protocols; others can be identified b y num ber
from 0-255, as defined by the Internet Assigned
Numbers Authority (IANA).
Apply Stateful Inspection
When this option is enabled, packets are
monitored for their state (i.e., whether a packet is
the initiating packet or a subsequent packet in an
ongoing communication, etc). This opti on
provides a degree of security by
blocking/dropping packets that are not received in
the anticipated state. Such packets can signify an
unwelcome attempt to gain access to a network.
CHAPTER-3
D-Link GLB-802C ADSL2+ Router User Manual 26
Field Description
Source/Destination Port
Port number criteria for the source computer(s)
(from which the packet originates) and
destination computer(s).
Port numbers identify the type of traffic that the
computer or server can handle and are specified
by the Internet Assigned Numbers Authority
(IANA). For example, port number 80 indicates a
Web server, 21 indicates an FTP server.
TOD Rule Status

Example
Blocking a specific computer on the LAN from accessing Web servers on the Internet:
• Add a new rule for outgoing packets on the ppp-0 interface from any incoming interface (this would
include the eth-0 and usb-0 interfaces).
• Specify the source IP address of the computer to be blocked.
• Specify the Protocol as TCP and enable the Store State setting.
• Specify the destination port as 80, which is the well-known port number for web servers.
• Enable the rule by clicking the radio button at the top of the page.
• Click submit to create the rule.
• On the IP Filter Configuration page, set the Security Level to the same level which is chosen for the
rule, and set both the Private Default Action and the Public Default Action to Accept.
• Click submit.
With this configuration, the specified computer will not be able to access the Web, but will be able to access
FTP Internet sites (and any others that use destination port numbers other than 80).

3.3.7.4 DNS
DNS servers map the user-friendly domain names that users type into their Web browsers (e.g.,
"yahoo.com") to the equivalent numerical IP addresses that are used for Internet routing.
Configuring DNS Relay
When the device's LAN interface IP address is specified as the DNS address, then the ADSL/Ethernet
automatically performs DNS relay; i.e., because the device itself is not a DNS server, it forwards domain
name lookup requests that it receives from LAN computers to a DNS server at the ISP. It then relays the
DNS server's response to the PC.
3.3.7.5 DDNS
Dynamic DNS (DDNS) is a service that facilitates outside Internet access to a LAN host even when the
host's dynamically-assigned IP address changes frequently.
a. Add the DDNS host address registered with the DDNS provider (For eg: test.dynalias.org)
a. Select the interface (Interface connected to the Internet i.e. ppp-0), select the DDNS
provider under “Service name “.
b. Enter the username and password for the DDNS account.
