What are the specific ports used for the Dropbox synchronization?

[Pennside I.]

I'm looking to segregate the traffic on our network by finding the ports used by Dropbox. Does anyone know what they are?

[Rick_M]

TCP/UDP port 17500 for lan sync and

HTTP

80, 8080

Hyptertext Transfer Protocol. Used by web browsers ...

HTTPS

443

Used for secure web browsing

for starters

Hi can anyone specify what port the desktop client uses?

See: https://www.dropbox.com/en/help/23

Dropbox executables (installer, app and updates) use port 80 and 443.

Some features use port 17600 and 17603.

Lan Sync use 17500 by default.

Dropbox.com needs to be whitelisted in some firewalls, NAC or IDS devices.
