I've followed the k3s tutorial and set up 1 remote node. However, I cannot seem to get the dns to work even though all nodes are able to ping each other.

/ # nslookup google.com
;; connection timed out; no servers could be reached

I encountered the same issue before when my local nodes can resolve the ns but my remote ones can't. (It seems to be related to coredns on the master as my remote nodes work with a default dns policy) Am I missing any settings? I'm not rly familiar with network concepts.
