Network	security
This chapter shows how to set up security defence for your local area network.
Setting	up	access	right	to	DSL-N13
To  protect  your  wired  and  wireless  LAN,  we  recommend  setting  up  access  protection  
so as to prevent DSL-N13 from being viewed or modified by unauthenticated users.
Service	restriction
DSL-N13  provides  a  Service  Control  List  (SCL)  that  can  enable  or  disable  services 
which  are  used  to  access  the  router  configuration  interface.  You  can  choose  allowing 
HTTP,  ICMP  from  WAN,  or  allowing  HTTP  from  LAN. After  configuration  is  complete, 
click Save/Apply to activate the settings.
IP	address	restriction
To protect the router from being accessed by unauthenticated user in your LAN, you can 
restrict  the  access  right  to  the  hosts  with  certain  IP  addresses.  Click Management 	-> 	
Access 	Control 	-> 	IP 	Addresses 	to setup the IP address for the authenticated network 
supervisors.  
Before  setting  up  the  IP  address  restriction,  make  sure  addresses  of 
authenticated hosts are static.

Password	protection
DSL-N13  ADSL  also  provides  three  levels  of  access  right:  admin,  support,  and  user. 
Account  "admin"  has  full  access  to  change  and  view  configuration  of  the  router, 
"support"  is  for  ISP  technician  to  view  and  keep  maintenance  to  the  router,  "user"  can 
view the router settings and statistics, as well as to update the software. 
1.  Click Management 	-> 	Access 	Control 	-> 	Passwords  in  the  left  side  menu  to 
setup passwords for these accounts. 
2.   Select  the  account  username  and  fill  in  old  password,  and  new  password  (twice). 
Each passwords contains up to 16 characters or digits. 
3.  Press Save/Apply 	to save and activate the settings.
Setting	up	port	triggering
Some  applications  such  as  games,  video  conferencing,  and  remote  access  require 
specified  ports  in  the  firewall  to  be  opened  for  remote  access.  You  can  configure  the 
port settings by selecting an existing application or creating your custom applications.

1.  Click Advanced 	Setup 	-> 	NAT 	-> 	Port 	Triggering in the left side menu to open the 
configuration page. Click Add to create a new rule.
2.   Select the service you want to configure and let the system automatically fill in the 
external  and  internal  port  number  and  protocol  type.  You  can  also  select Custom 	
Server radio button to designate a certain known server.
3.  Fill  in  trigger  port  (range)  and  protocol,  open  port  (range)  and  protocol  for  the 
service if you select Custom 	Server radio button.
4.   Press Save/Apply to save and activate the settings.
Setting	up	virtual	server
Vitual  server  allows  directing  WAN  incoming  traffic  to  hosts  or  servers  using  private  IP 
addresses  within  a  LAN.  With  virtual  server,  the  router  checks  the  port  number  of  the 
packets sent to the WAN interface, translates the port numbers into private IP address, 
and  redirects  the  packets  to  the  corresponding  internal  hosts  and  servers.  DSL-N13 
supports up to 32 virtual server entries. To set up virtual server:
1.  Click Advanced 	Setup 	-> 	NAT 	-> 	Virtual 	Server in the left side menu to open the 
configuration page. Click Add to create a new rule.
2.   Select the service you want to configure and let the system automatically fill in the 
external  and  internal  port  number  and  protocol  type.  You  can  also  select Custom 	
Server radio button to designate a certain known server.
3.  Fill in external port (range), internal port (range), and protocol for the service if you 
select Custom 	Server radio button.
4.   Fill the Server 	IP 	Address box with the network address of the host or server within 
your LAN.
5.   Press Save/Apply to save and activate the settings.

Setting	up	DMZ	host
The  function  of  DMZ  is  similar  to  that  of  virtual  server.  The  difference  between  vitual 
server  and  DMZ  is  that  DMZ  opens  all  ports  to  WAN  while  virtual  server  opens  ports 
according to the demand of the enabled services. To configure DMZ host:
1.  Click Advanced 	Setup 	-> 	NAT 	-> 	DMZ 	Host  in  the  left  side  menu  to  open  the 
configuration page. 
2.   Enter the IP address of the host to be setup as DMZ host.
3.  Press Save/Apply to activate the settings.
Allowing SIP request through NAT
NAT  checks  IP  header  only  and  translate  the  information  into  private  IP  address. 
However, for applications that demand many dynamic ports for session control such as 
Session  Initiation  Protocol  (SIP),  traditional  NAT  cannot  translate  the  address  because 
lack  of  preset  service  ports.  To  enable  such  services  while  at  the  same  time  do  not 
sacrifice  network  security,  DSL-N13  introduces  Application  Layer  Gateway  (ALG)  to 
allow SIP request going through fireware and NAT from WAN. To configure ALG: 
1.  Click Advanced 	Setup 	-> 	NAT 	-> 	ALG  in  the  left  side  menu  to  open  the 
configuration page. 
2.   Select SIP 	Enabled checkbox to allow SIP request, or uncheck to disable. 
3.   Press Save/Apply to save and activate the settings. 
Firewall - Outgoing IP filter
By default, all outbound IP traffic is allowed. You can block certain types of IP traffic by 
setting up filter rules at DSL-N13.
1.  Click Advanced 	Setup 	-> 	Security 	-> 	IP 	Filtering 	-> 	Outgoing  in  the  left  side 
menu to open the configuration page. Click Add to create a new rule.

2.  Define a Filter 	Name for the filter rule. Specify protocol, source IP address, subnet 
mask and port (range) and destination IP address, subnet mask and port (range).
3.   Press Save/Apply to save and activate the settings. 
Firewall- Incoming IP filter
By default, all incoming IP traffic is blocked. You can allow certain types of IP traffic by 
setting up filter rules at DSL-N13.
1.  Click Advanced 	Setup 	-> 	Security 	-> 	IP 	Filtering 	-> 	Incoming  in  the  left  side 
menu to open the configuration page. Click Add to create a new rule.
2.   Define a Filter 	Name for the filter rule. Specify protocol, source IP address, subnet 
mask and port (range) and destinationi IP address, submask and port (range).
3.   Select the WAN interface through which the packets enter the firewall. 
4.  Press Save/Apply to save and activate the settings.

Access	time	restriction
This  function  enables  to  put  time  restriction  on  Internet  access  by  setting  up  blocking 
time table. To configure the access time restriction:
1.  Click Advanced 	Setup 	-> 	Security 	-> 	Parental 	Control 	in  the  left  side  menu  to 
open the configuration page. Click Add to create a new rule.
2.  Fill in the User name to whom you want to apply the restriction.
3.  Fill in the MAC address of the restricted host. If you are accessing this configuration 
at the computer of restricted host, select Browser's MAC Address radio button. The 
system automatically detects the MAC address of the configuration console. If you 
want  to  configure  hosts  other  than  the  console  computer,  enter  the  MAC  address 
manually. 
To  get  the  MAC  address  of  a  host,  click Start 	menu  on  the  desktop  of 
the  host,  select Run...,  type cmd  into  the  box  and  press OK,  then  type 
command ipconfig 	/all  and  press  enter.  You  can  find  the  MAC  address 
displayed as Physical 	Address.
4.   Select the days of a week to which the rule shall apply.
