Looks like per - https://github.com/opnsense/docs/blob/master/source/manual/how-tos/dnscrypt-proxy.rstYou have to add your LAN ip to the listening port as well at the bottom of the page -----Now change to Services->DNSCrypt-Proxy->Configuration and add your Local LAN IP address to the Listen Address field, e.g. 192.168.2.1:53.Optionally you can set :53 to listen on all addresses like the default behaviour in Unbound.
