No Internet connected server should be without a firewall. This important tool provides administrators with the ability to select what resources are available from the Internet while protecting other resources from intruders. 602Pro LAN SUITE 2003’s built-in firewall makes this process a snap.

Turning on the Firewall

If you have upgraded from 602Pro LAN SUITE 2003, the firewall is NOT enabled by default, or perhaps you did not enable the firewall after installing 602Pro LAN SUITE 2003. Follow these directions to turn the firewall on:

1. Open 602Pro LAN SUITE.
2. Click Settings then Advanced Configuration.
3. Click the Firewall tab, then check the Firewall checkbox.
4. To the right of the checkbox, you will need to select what network interfaces are for the Local Area Network (e.g. your LAN or other trusted network). This is very important because we do not want to block your internal network users from accessing server resources. Simply click the checkbox to add a check mark in the box next to the appropriate network interface.
5. Click Save.

NOTE: The Firewall feature is only available for Windows 2000, Windows XP and Windows Server 2003.

Provide access to LAN SUITE resources

By default, the security level is set to Medium, which means all connections from the Internet are rejected unless a connection is requested from the internal network, but all connections from the internal network are accepted. This means that any resources you wish to allow access to from the Internet will not be available. To change this you will need to simply set the security level to Custom, then select the resources you would like to allow access to.

1. Open 602Pro LAN SUITE.
2. Click Settings then Advanced Configuration.
3. Click the Firewall tab, then move the Security slider to Custom.
4. Click Reset to default, then choose Yes.

Now you may simply uncheck the checkbox next to the resources you would NOT like to be accessible from the Internet. For example, if you do not wish to provide access to the LDAP directory from the Internet, simply remove the checkmark next to the LDAP entry on the list. Likewise, if you wish to allow access to Remote Administration or the Web mail client from the Internet, you must make sure the WWW entry is checked.
