Hi! Is there a page that explains how the FWG intercepts DNS requests from devices in the LAN? Basically trying to understand how it works underneath the hood. Does it just block port 53? Also 853? Does it maintain a list of DNS (and DoH?) servers and also block those requests? Thx!

  The intercept is done in the data path, I think the match is port 53. There is no block, just forward port 53 to firewalla. DoH there is a target list you can use to block them. (experimental)
