I was recently given an Umbrella SIG Advantage lab account, which I gleefully associated with my Meraki home lab network, using the Cloud On-Ramp feature and configuring my MX up as a VPN spoke. First I used the US East coast servers, then I used the US West Coast servers, and minimal policy setting.
I have to say, it has not been the most impressive experience. Very slow performance, several pages stalling out altogether, and frequent notifications of VPN disconnections, even with just default Umbrella SIG policies set. I have completely broken it down and built it back up at least 3 times. I am curious to know if folks have been having similar experiences or whether I need to have a go at it again.
