Severity: 3-Major


When a virtual server is configured with a destination address list, some of the address ranges within the list may be configured as a subnet virtual address. Subnet virtual addresses do not respond to ARP and ICMP echo.


Addresses may behave differently in a destination address list depending on whether the address is configured as a host or as part of a range. Note: This is by design and functions the same as a network virtual server, where ARP and ICMP echo are not enabled by default.


A virtual server is configured with destination address list, that contains address ranges.


If the addresses of a destination address list are desired to behave as hosts, then do not add address ranges to the list, but add them as a list of individual addresses.
