2.3 Configuring Firewalls

Most software firewalls detect Lasso CDP during installation and prompt for permission to

open the appropriate ports. If you have a firewall installed you will need to configure it

before using the Lasso CDP Client or Lasso CDP Appliance.

2.3.1 Windows XP SP2

Windows XP SP2 installs and activates a firewall by default. If you applied Service

Pack 2 after installing the Lasso CDP Client software, you may need to add

CDPAgent.exe and Lasso.Client.exe to Windows XP Internet Connection Firewall

settings before the backup service can start again. Microsoft has excellent

instructions on how to do this here:

To enable or disable Windows XP Internet Connection Firewall:

• Open the Network Connections control panel (Start > Control Panel).

• Click the LAN or high-speed Internet connection that you are using under

Network Tasks in the left window

• Click Change Windows Firewall Settings. In this menu you can simply select

off, then click OK.

2.3.2 McAfee Personal Firewall

Note: If you are using Windows XP SP2, make sure you have configured XP's

firewall first, using the instructions above.

If you are using a McAfee firewall product you will likely see warnings when

starting the Lasso CDP Client such as the following (Figure 10). In both cases,

select Grant Access.
