If I install the Symantec Client Security Firewall, can I continue to run the Windows XP SP2 Firewall?
It is recommended that you run only one host firewall on your system. Windows XP SP2 firewall can coexist with third-party firewalls such as the one included in Symantec Client Security; however, multiple firewalls don’t increase your safety. Running multiple firewalls means that you will need to configure settings in multiple places.
