Title: dropbox as client networkdrive is blocked on transparent proxy
Post by: opnsenseuser on October 20, 2018, 04:00:25 pm

hope someone can help me or just give me a good advise!

i use transparent squid proxy with cert for https and http.

i have a problem using dropbox as a networkdrive for uploading and syncing!

1. i opened up ports 17500, 17600 and 17603!
https://www.dropbox.com/en/help/desktop-web/configuring-firewall (https://www.dropbox.com/en/help/desktop-web/configuring-firewall)

2. i made a no rdr rule for traffic the goes directly to dropbox.com and http://dropbox.com by alias!
i even pinged the url to get the ip´s and and entered them to alias list too.
3. i added the ip of dropbox.com to "unrestricted ip adresses" under access control list.
4. i added "*.dropbox.com, .dropbox.com " to the whitelist.
5. i added ".dropbox.com" to the no ssl bump sites.

but i only get my networkdrive working for uploading and syncing by completely disable the nat rules for transparent proxy. "No RDR" doesn´t work and i found no solution in the forum.
Entering the dropbox by browser works but networkdrive can´t establishe any connection.
Firewall log says nothing!

can someone help me find the problem ?

regards
rené

I misspelled the entry in the "no ssl bump" section. I wrote ".dropbox" and forgot ".com".
After I have corrected this, everything now works as it should.
