Chapter 5 Configuring the Router’s Security

Note that it is the origin of the request, not subsequent responses to this request,

which determines whether a session can be established or not.

The Router features three pre-defined security levels: Minimum, Typical, and

Maximum. The table below summarizes the behavior of the Router for each of the

three security levels.

Security Level

Requests from the Internet

(incoming traffic)

Requests from the local

network (outgoing traffic)

Maximum

Security

Blocked - No access to local

network from Internet,

except as configured in the

Port Forwarding, DMZ host,

and Remote Access screens.

Limited - Only commonly

used services, such as web

browsing and E-mail, are

permitted.

Typical Security

Blocked - No access to local

network from Internet,

except as configured in the

Port Forwarding, DMZ host,

and Remote Access screens.

Unrestricted - All services

are permitted, except as

configured in the Access

Control screen.

Minimum

Security

Unrestricted - Permits full

access from Internet to local

network; all connection

attempts permitted.

Unrestricted - All services

are permitted, except as

configured in the Access

Control screen.

These services include Telnet, FTP, HTTP, HTTPS, DNS, IMAP, POP3 and SMTP.

☞

Note: Some applications (such as some Internet messengers and

Peer-To-Peer client applications) tend to use these ports if they

cannot connect with their own default ports. When applying

this behavior, these applications will not be blocked outbound,

even at the Maximum Security level.

To configure the Router’s security settings:

1. From the General screen, select a security level by clicking the appropriate radio

button. Using the Minimum Security setting may expose the local network to

significant security risks, and thus should only be used for short periods of time.
