It seems that Dropbox hits port 17500 pretty hard and pretty continuously looking for other machines running Dropbox.  The traffic is excessive.  It would work as well if Dropbox installations announced themselves on boot and did the query, say, every 5 minutes.

Is there any way to keep Dropbox from doing this search, or get it to do the search at a more reasonable rate?

Hi @alwhaley; how are you today?

I'm sorry to jump in; I just wanted to add my 2 cents here.

What you see might be actually expected as the port 17500 is used to enable our desktop app to use the LAN sync feature

If you'd like to disable that option, you can do it via the desktop app's preferences under the Network tab

If you need any assistance with configuring your firewall to work with Dropbox, you can take a look at the relevant resource:

I hope this helps clear this up a tad, and we're always a post away should you have any follow up questions.

Typical entry in firewall logs:

Feb 4 07:27:00 routr0 kernel: [5356166.316824] %_4_DROPBOX_HIT IN=enp6s0f3 OUT= MAC=ff:ff:ff:ff:ff:ff:a8:20:66:45:b3:43:08:00 src=10.1.12.8 DST=255.255.255.255 LEN=160 TOS=0x00 PREC=0x00 TTL=64 ID=9533 PROTO=UDP SPT=17500 DPT=17500 LEN=140

Destination MAC address is all FF's.  Protocol is 08:00.  The rest is pretty much self explanatory.

Thanks for the suggestion. Although I did disable LAN sync (after I figured out how to find prefs on the Mac) and that does get rid of the repetitive broadcast message, it would be nice if Dropbox could sync without constantly acting dumb and broadcasting to the entire network. The only way to keep it from broadcasting is to disable a feature that shouldn't need it. Other services manage to sync over a network without that constant blind query.
