Can't make v2ray to send DNS queries to its localhost

Question

There are two v2ray servers A and B with similar configurations but A works as an intermediary (vmess+websocket on both inbound and outboud) to reach B.

I want to make A to send incoming DNS queries to its localhost:53 where CoreDNS is listening on. How to do it?

I've done this in A:

... { "protocol": "dns", "tag": "dns_out", "settings": { "address": "localhost", "port": 53 } } ], "dns": { "queryStrategy": "UseIPv4", "servers":["localhost"], "tag": "dns_inbound"} }, "routing": { "domainStrategy": "IPOnDemand", "rules": [ { "type": "field", "port": 53, "network": "tcp,udp", "outboundTag": "dns_out" } ] } } 

But why v2ray A always chooses the default route (of two routes: protocol vmess and protocol dns) and sends no DNS queries to CoreDNS on localhost:53?

Answer 1

The problem was an extra } where I specify tag for dns. And v2ray was fine with it, ignoring rest of it.
