Prevent Bonjour Announcements Over OpenVPN We have an OpenVPN server at work, which I use frequently to access private work resources. When I do, the "Shared" listed in Finder populates with all the automatically announced servers/resources at work, but the reverse is also true. My local resources appear to anyone at work, and/or on the VPN as well.

Ideally, I would like to prevent my announcements from going over the VPN link, but would like to have the shares physically at work available to me while on the VPN. If the only method is to disable Bonjour (temporarily), I'll be fine with that, but is there a way to make it only one-sided?

And of course the master question: How do I accomplish this, at all, in the first place.
How about blocking udp traffic on port 5353?
