SPI  (Stateful  Packet  Inspection,  also  known  as  dynamic  packet 
filtering) helps to prevent cyber attacks by tracking more state per 
session.  It  validates  that  the  traffic  passing  through  the  session 
conforms to the protocol.
Select one of the following for TCP and UDP ports:
Endpoint Independent - Any incoming traffic sent to an open port 
will be forwarded to the application that opened the port. The port 
will close if idle for 5 minutes.
Address Restricted - Incoming traffic must match the IP address 
of the outgoing connection.
Address + Port Restriction - Incoming traffic must match the IP 
address and port of the outgoing connection.
If  an  application  has  trouble  working  from  behind  the  router,  you 
can  expose  one  computer  to  the  Internet  and  run  the  application 
on that computer.
Note: Placing a computer in the DMZ may expose that computer to 
a variety of security risks. Use of this option is only recommended 
as a last resort.
Specify the IP address of the computer on the LAN that you want to 
have unrestricted Internet communication. If this computer obtains 
it’s IP address automatically using DHCP, be sure to make a static 
reservation  on  the  Basic  >  DHCP  page  so  that  the  IP  address  of 
the DMZ machine does not change.

Firewall Settings
A firewall protects your network from the outside world. The D-Link DIR-635 offers a firewall type functionality. The SPI 
feature helps prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain 
types of applications. If you choose to expose a computer, you cam enable DMZ. DMZ is short for Demilitarized Zone. 
This option will expose the chosen computer completely to the outside wo\
rld.

Application Level Gateway (ALG) Configuration
Here you can enable or disable ALG’s. Some protocols and applications require special handling of the IP payload to 
make them work with network address translation (NAT). Each ALG provides special handling for a specific protocol 
or application. A number of ALGs for common applications are enabled by \
default.
Allows multiple machines on the LAN to connect to their corporate networ\
k using PPTP protocol. 
Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec 
through NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your 
corporate network, try turning this ALG off. Please check with the system adminstrator of your corporate network whether 
your VPN client supports NAT traversal.
Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and 
Real Player are some of the common applications using this protocol. 
Allows all of the Windows/MSN Messenger functions to work properly throu\
gh the router.
Allows FTP clients and servers to transfer data across NAT. Refer to the Advanced > Virtual Server page if you want to 
host an FTP server. 
Allows Microsoft NetMeeting clients to communicate across NAT. Note that if you want your buddies to call you, you should 
also set up a virtual server for NetMeeting. Refer to the Advanced > Virtual Server page for information on how to set up 
a virtual server. 
Allows  devices  and  applications  using  VoIP  (Voice  over  IP)  to  communicate  across  NAT.  Some  VoIP  applications  and 
devices have the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such 
devices. If you are having trouble making VoIP calls, try turning this A\
LG off. 
Allows Ethernet network adapters with Wake-On-LAN (WOL) to function.
Allows Windows Media Player, using MMS protocol, to receive streaming me\
dia from the internet.

Set the transmit power of the antennas.
Beacons  are  packets  sent  by  an  Access  Point  to 
synchronize  a  wireless  network.  Specify  a  value. 
100 is the default setting and is recommended. 
This  value  should  remain  at  its  default  setting  of 
2432. If inconsistent data flow is a problem, only a 
minor modification should be made.
The  fragmentation  threshold,  which  is  specified 
in  bytes,  determines  whether  packets  will  be 
fragmented.  Packets  exceeding  the  2346  byte 
setting  will  be  fragmented  before  transmission. 
2346 is the default setting. 
(Delivery Traffic Indication Message) 3 is the default 
setting.  A  DTIM  is  a  countdown  informing  clients 
of  the  next  window  for  listening  to  broadcast  and 
multicast messages.
This enables 802.11d opration. 802.11d is a wireless specification developed to allow implementation of wireless networks in 
countries that cannot use the 802.11 standard. This feature should only \
be enabled if you are in a country that requires it.
WMM  is  QoS  for  your  wireless  network.  Enable  this  option  to  improve  the  quality  of  video  and  voice  applications  for  your 
wireless clients.
Check this box to reduce the guard interval time therefore increasing the data capacity.  However, it’s less reliable and may 
create higher data loss.
