Dropbox - How to Enable LAN Sync

December 2016

The LAN Sync feature can speed up the syncing of files that exist on your local area network (shared folders and computers connected to the network). It allows Dropbox to check for new versions of a file on your network without having to download the copy of the latter from Dropbox servers.

Enabling the LAN Sync feature is straightforward procedure, provided that all the computers are connected to the same subnet (a local network with a single router):


Install the Dropbox client on your PC: www.dropbox.com.

Allow Dropbox.exe in your firewall's settings: The LAN Sync feature requires access to port 17500 (TCP). Go to the Control Panel > Firewall > Allow app or feature through Windows Firewall.

Enabling LAN Sync:

Click on the Dropbox tray icon > Preferences. Go to the Bandwidth tab and tick the Enable LAN sync checkbox:

Click on Apply > OK.
