PORT FORWARDING TAB
Use this page to manage your LaCie NAS's port forwarding.
To access the internet, file and application services (e.g. HTTP, HTTPS, remote access (see LaCie MyNAS),
download machine, and more) use port numbers on the LaCie NAS and the network router. As seen in the
screenshot above, automatic port forwarding is turned on by default and the port numbers are the same for
both the NAS port and Router port columns.
In most instances, automatic port forwarding should help you access services on the NAS. However,
enterprise-level network security or port availability on your router can prevent access to ports. Therefore, it
may be necessary to change the router port numbers manually for services. Before adjusting numbers in this
tab, confirm that the ports you wish to use are available on your router. For example, if you intend to change
download machine to router port number 8800, you must make certain that port 8800 is available on your
router. Additionally, your router must be compatible with UPnP-IGD/NAT-PMP protocols. See your router's user
manual for details.
To change the router port for a service on the NAS, choose its value in the Router port column.
