Need help routing only Google Drive desktop app traffic through a specific gateway
-
I tried doing some searches and couldn't find anything here that would answer my question.
I work for an MSP locally here in Utah and I have a client that is using a dedicated firewall device running 2.7.0-Release. They just had a dedicated fiber optic line run from their site directly to Google's datacenters to allow for a direct-connect. We got the BGP session initiated and the two BGP neighbors are communicating. This dedicated pipe is not a traditional gateway and will not work for normal web traffic. The client set it up because they relocated their entire fileserver to Google Drive and were tired of using VPN's. I followed a KB from Google that's supposed to only route Drive traffic but when I enable the rules for it, it routes ALL Google traffic even from the web, which then breaks their browsing because this pipe is not a traditional gateway. Here's the KB: https://apps.google.com/supportwidget/articlehome?hl=en&article_url=https%3A%2F%2Fsupport.google.com%2Fa%2Fanswer%2F2589954%3Fhl%3Den&assistant_id=generic-unu&product_context=2589954&product_name=UnuFlow&trigger_context=a
I haven't set any NAT rules up yet; should I? I was thinking of going through that list again and start stripping things out that look like it's not related to Drive specifically. I have pfBlockerNG installed but nothing setup yet.
Any help would be greatly appreciated. Thanks!
