The zone overlap validation rejected this configuration when the unfiltered block was not declared last, because filtered configs treated an already-registered zone as an error. Skip the 'already defined' check for configs that have filter functions, since they are expected to coexist with an unfiltered catch-all block on the same zone/port.

Summary
PROXY protocol support was introduced in CoreDNS 1.24.1 in #7738. But when PROXY protocol is enabled on the DoH server,
DoHWriter.laddralways used the static listener address (s.listenAddr) instead of the per-connection destination address from the PROXY protocol header. This is incorrect when the server is behind a load balancer with VIPs, and defeats the purpose of PROXY protocol.http.Server.ConnContextto capturec.LocalAddr()per connectionlocalAddr()helper that reads from context withs.listenAddras fallbacks.listenAddrwiths.localAddr(r)inServeHTTPNote:
r.RemoteAddr(used forraddr) is already correct for TCP — Go'snet/httpreads it fromproxyproto.Conn.RemoteAddr()through the TLS chain.Test plan
