By

the

uses

the

IP

address

from
the
real

or

virtual

server

configuration

for

the

destination

IP

address.

To

Note
The
following

support

IPv6

destination

HTTP,

HTTPS,

ICMP,

TCP,

and

Note
When
you

assign

a

probe

to

a

server,
they

must

be
configured
with

the

type
(IPv6

•
The
port

for
t

he
probe.

•
The

number

from

the
