Establishing an

Authenticated

Session

Authenticated Sessions allow a user on the Internet to access the LAN

without restrictions, or allow a user on the LAN to access the Internet

without restrictions, bypassing the Web Site Filters.

Make sure that the Web browser software being used to establish an

authenticated session support Java, JavaScript or ActiveX scripting.

To establish an Authenticated Session, you point your Web browser at the

Firewall’s LAN IP Address. This process is identical to the administrator

A dialog box is displayed, asking you for the user name and password.

After filling in these boxes and clicking Login, the password is verified

using MD5 authentication. The password is never sent ”in the clear” over

the Internet, preventing password theft and replay attacks.

Once authenticated, remote users can access all IP resources on the LAN,

and users on the LAN can bypass the Web Site Filter. The connection

closes if user inactivity on the connection exceeds the configured

time-out period. In that case, the remote user must re-authenticate. If it

seems like authentication is failing for no reason, make sure that the Caps

Lock key on the keyboard is not on.

NAT must not be enabled for remote authenticated access.
