three security levels.

These services include Telnet,
☞
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.
