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.

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

configuration page. Click
