I tried to test drive the free tunnel service but when DNS moved over to Cloudflare some VOIP devices could not connect to the A record I used for them previously. The record resolved but somehow interfered with the connections to it, any advice as I really want to try your tunnel product and possibly other products too!
Did I miss some security rule that would have somehow affected VOIP clients connecting to my A record after it was changed to Cloudflare dns?
