Appendix A - Firewall
STATEFUL PACKET INSPECTION
Refers to an architecture, where the firewall keeps track of packets on each
connection traversing all its interfaces and makes sure they are valid. This is in
contrast to static packet filtering which only examines a packet based on the
information in the packet header.
DENIAL OF SERVICE ATTACK
Is an incident in which a user or organization is deprived of the services of a
resource they would normally expect to have. Various DoS attacks the device can
withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf
Attack, and Tear Drop.
TCP/IP/PORT/INTERFACE FILTER
These rules help in the filtering of traffic at the Network layer (i.e. Layer 3).
When a Routing interface is created, Enable Firewall must be checked.
Navigate to Advanced Setup Security IP Filtering.
OUTGOING IP FILTER
Helps in setting rules to DROP packets from the LAN interface. By default, if the
Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more
filters, specific packet types coming from the LAN can be dropped.
Example 1: Filter Name

destined to 172.16.13.4/24 and a destination port range of 6060 to 7070.
INCOMING IP FILTER
Helps in setting rules to Allow or Deny packets from the WAN interface. By default,
all incoming IP traffic from the WAN is Blocked, if the Firewall is Enabled. By setting
up one or more filters, specific packet types coming from the WAN can be Accepted.

of 6060 to 7070. All other incoming packets on this interface are DROPPED.
MAC LAYER FILTER
These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in
Bridge mode. After a Bridge mode connection is created, navigate to Advanced
Setup Security MAC Filtering in the WUI.

The PPP Username, PPP password and the PPPoE Service Name entries are
dependent on the particular requirements of the ISP. The user name can be a
maximum of 256 characters and the password a maximum of 32 characters in
length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
158
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
DIAL ON DEMAND
The NexusLink 3112u can be configured to disconnect if there is no activity for a
period of time by selecting the Dial on demand checkbox . You must also enter
an inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
•
•
•
•
•
•
Allows only one PC on the LAN.
Disables NAT and Firewall.
The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox should not be selected to free up system
resources for better performance.
ENABLE FIREWALL
If this checkbox is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox
should not be selected to free up system resources for better performance.
USE STATIC IPv4 ADDRESS
Unless your service provider specially requires it, do not select this checkbox . If
selected, enter the static IP address in the IPv4 Address field.
Don’t forget to adjust the IP configuration to Static IP Mode as described in section
3.2.
159
FIXED MTU
Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which
the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS
(This option is hidden when PPP IP Extension is enabled)
When Enabled, this creates local PPPoE connections to the WAN side. Enable this
option only if all LAN-side devices are running PPPoE clients, otherwise disable it.
The NexusLink 3112u supports pass-through PPPoE sessions from the LAN side
while simultaneously running a PPPoE client from non-PPPoE LAN devices.
ENABLE IGMP MULTICAST PROXY
Tick the checkbox to enable Internet Group Membership Protocol (IGMP)
multicast. This protocol is used by IPv4 hosts to report their multicast group
memberships to any neighboring multicast routers.
NO MULTICAST VLAN FILTER

an inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
•
•
•
•
•
•
Allows only one PC on the LAN.
Disables NAT and Firewall.
The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox should not be selected to free up system
resources for better performance.
