A bastion host is a system visible to the Internet. When intranet users need Internet access, the request is sent to a known port on the host. Gateway software installed on the host validates a TCP or UDP session before a opening a connection or circuit. The host services the request and can substitute its own IP address for that of the requestor. This substitution process is referred to as a proxy mechanism.
