External clients must use public IP addresses configured in the network address translation (NAT) device. The NAT device uses static NAT to convert the public addresses to the internal VIPs configured on the load balancer.\n\nNetwork Time Protocol\n\nAll the VMs that are part of your Google Distributed Cloud infrastructure must\nuse the same\n[Network Time Protocol (NTP)](http://www.ntp.org/ntpfaq/NTP-s-def.htm)\nserver."]]
