F-2 INSTALLING TELEVANTAGE
For a complete list of the Windows Firewall exceptions added by TeleVantage and their
associated default values, see “Windows Firewall exceptions added for TeleVantage” on
page F-4.
You must change the default firewall security settings using the TeleVantage Administrator
according to the instructions in “Adjusting Windows Firewall exceptions” on page F-2 if either
of the following are true:
Q Your TeleVantage Server and workstation PCs are not all located on one subnet.
Q Your TeleVantage Server’s IP address can change because you use DHCP to obtain an
IP address automatically
If you do not make these changes, TeleVantage workstation applications such as ViewPoint may
not operate properly (for example, calls will not appear in the Call Monitor.)
Adjusting Windows Firewall exceptions
Perform the following procedure on any TeleVantage Server that is running Windows XP
SP2/Windows Server 2003 SP1. Your changes will be picked up by workstation PCs the next
time that they connect to the Server.
1. Start the TeleVantage Administrator and choose
Tools > System Settings.
2. Select the Security \ Server Firewall tab.
The settings on the Security \ Server Firewall tab determine which IP addresses will
be allowed to communicate with the TeleVantage Server PC, including the IP
addresses of any PCs that will be running TeleVantage workstation applications such
as ViewPoint.
3. Choose one of the following options to define the scope for the Windows Firewall
exceptions required by TeleVantage:
Q Any computer (including those on the internet). With this option, the
TeleVantage Server PC accepts network traffic from all IP addresses. TeleVantage
connections will always work with this setting.
Important:
This setting leaves your Windows PC the most vulnerable to
potentially harmful connections.
Q My network (subnet) only. With this option (the default setting), the TeleVantage
Server PC accepts traffic only from other TeleVantage PCs within your subnet.
The range of your subnet is defined by your subnet mask, which is usually
255.255.255.0. For example, with an IP address of 192.168.114.20 and subnet mask
255.255.255.0, the PC would accept communication from IP addresses
192.168.114.1 through 192.168.114.255.
