If the computers that run Symantec Endpoint Protection Manager and the Symantec Endpoint Protection client also run third-party firewall software or hardware, you must open certain ports. These ports are for remote deployment and for communication between the management server and clients. See your firewall product documentation for instructions to open ports or allow applications to use ports.

By default, the firewall component of Symantec Endpoint Protection already allows traffic on these ports.

Warning:

The firewall in the Symantec Endpoint Protection client is disabled by default at initial installation until the computer restarts. To ensure firewall protection, leave the Windows firewall enabled on the clients until the software is installed and the client is restarted. The Symantec Endpoint Protection client firewall automatically disables the Windows firewall when the computer restarts.

  • Windows Vista and later contain a firewall that is enabled by default. If the firewall is enabled, you might not be able to install or deploy the client software remotely. If you have problems deploying the client to computers running these operating systems, configure their firewalls to allow the required traffic.

  • If you decide to use the Windows firewall after deployment, you must configure it to allow file and printer sharing (port 445).

For more information about configuring Windows firewall settings, see the Windows documentation.
