Dunno. I have blocked both UDP and TCP on my hidden primary, and it is refreshing its trust anchors via my recursive servers OK, so it is not something I have had to worry about. In general, port 53 should work for both UDP and TCP, or neither. If it's half-blocked you'll get weird problems, and the solution is to fix the network.

Very rough or high, becoming rough or very rough later in Lundy and Fastnet. Squally wintry showers.
