Configuring time synchronization
Use the firewall as a time server for the LAN. A time server is a computer that provides accurate time to
other computers on the LAN. This server increases security on the network by providing accurate time to
all hosts on the network so that auditing and logging entries have the correct time. In addition, many
network protocols require accurate time to function properly.
To obtain the most accurate time possible, the ProLiant DL320 Security Server must access a time server
on the Internet. If you choose not to have the ProLiant DL320 Security Server as a time server for the LAN,
configure the server to allow computers on the LAN to contact their own Internet time servers.
