NAME

icmphost - nominate a host to process ICMP packets
SYNOPSIS
icmphost [IPaddr]
DESCRIPTION
Command icmphost is used to specify the IP address of a private machine which is to receive ICMP ECHO and ICMP TIME EXCEEDED responses. If no argument is specified, the command prints the IP address of the machine to which ICMP responses are currently being sent.

If all machines, including the NAT32 machine are to receive ICMP responses, the IP address of the Primary Interface should be specified (this is the default).

NOTES
NAT32 will not forward ICMP responses if the current icmphost address is 0. In this case, command icmphost can be used to set a non-zero IP address.
