Configuring ESXi Firewall in the VMware Host Client
ESXi includes a rewall that is enabled by default. At installation time, the ESXi rewall is congured to
block incoming and outgoing trac, except trac for services that are enabled in the host security prole.
As you open ports on the rewall, consider that unrestricted access to services running on an ESXi host may
expose a host to outside aacks and unauthorized access. Reduce the risk by conguring the ESXi rewall to
allow access only from authorized networks.
N The rewall also allows Internet Control Message Protocol, or ICMP, pings and communication with
DHCP and DNS (UDP only) clients.
