Anyone know the best method to send particularly dropbox out a particular interface? Already have fail-over setup and working, I want everything to go by connection 1 by default, but dropbox and a few select services by connection 2. It's easy to do source/destination IP or port number, however I believe dropbox uses ports 80 and 443 which would mean all web traffic is going to get caught if i'm using destination port. And I don't believe there is a list of dropbox IP's to add to an address list

I've tried using the content field and putting in dropbox.com but when I do that I get NO traffic flow at all, completely dies. I'm assuming not all connections are matching the 'dropbox' rule so some things are going by connection 2, some by connection 1 causing an incomplete establishment

I won't swear by it, but this looks like what you are looking for: https://whois.arin.net/rest/org/DROPB/nets
