Access can be restricted to the local host or to the machines on a list, or access can granted to all.
Restricting access to the local host only works if only the local machine will put in requests to the ITP/Server. In reality this situation will not often occur. However, this setting might be useful during development.
The access list is a comma-separated list of IP numbers of the machines that must have access. It is also possible to grant a whole range of machines access by using the CIDR notation in the list. For example:
Network access list: 10.0.0.0/24
This setting will grant access to all machines in the range 10.0.0.0 to 10.0.0.255.
Refer for more information to the Help of the ITP/Server Administrator.
The option No access restrictions can be used to allow all machines access.
