PCAnywhere and Timbuktu

If your computer is either the host or the client of a remote access system such as PCAnywhere or Timbuktu:

1. Add the IP address(es) of the hosts or clients to which you connect to your Trusted Zone. How?
2. Add the subnet of the network you are accessing remotely to your Trusted Zone.
3. If a dynamic IP address is assigned to the remote machine, add the DHCP server address or range of addresses to the Trusted Zone.

Note If your remote control client or host is on a network not under your control (for example on a business or university LAN), perimeter firewalls or other features of the network may prevent you from connecting. If you still have problems connecting after following the instructions above, contact your network administrator for assistance.

VNC

In order for VNC and ZoneAlarm Pro to work together, follow the steps below.

1. On the server machine, do one of the following:
   - If you know the IP address or subnet of the viewer (client) you will be using for remote access, and it will always be the same, add that IP or subnet to the Trusted Zone. This is the preferred option.
   - If you do not know the IP address of the viewer, or it will change, then give the program access permission and server permission for the Trusted and Internet Zones.
2. On the viewer (client) machine, run VNCviewer to connect to the server machine. Do not run in "listen mode."
3. On the viewer (client) machine, do one of the following:
   - If you know the IP address or subnet of the server, and it will always be the same, add that address or subnet to the Trusted Zone. This is the preferred option.
   - If you do not know the IP of the Server, or it will change, then give the program access permission and server permission for both the Trusted Zone and Internet Zone.
   
4. When prompted by VNCviewer on the viewer machine, enter the name or IP address of the server machine, followed by the password when prompted. You should be able to connect.

Caution If you enable VNC access by giving it server permission and access permission, be sure to set and use your VNC password in order to maintain security. We recommend adding the server and viewer IP addresses to the Trusted Zone, rather than giving the application Internet Zone permission, if possible.

Tip Leave the Trusted Zone security level on medium. If you raise it to high, you may have access problems.

To learn how to add IP addresses, subnets, or ranges to the Trusted Zone, or give access and server permissions to programs, see Related Topics.

Telnet

To access a remote server via Telnet, add the IP address of that server to your Trusted Zone.

DHCP (Dynamic Host Configuration Protocol)
A protocol used to support dynamic IP addressing. Rather than giving you a static IP address, your ISP may assign a different IP address to you each time you log on. This allows the provider to serve a large number of customers with a relatively small number of IP addresses.
