Can local-dns be bound on the local-tun interface address?

I've tried:

    {
      "protocol": "tun",
      "tun_interface_address": "10.255.0.1/24",
    },
    {
      "protocol": "dns",
      "local_address": "10.255.0.1",
      "local_port": 53,
      "local_dns_address": "114.114.114.114",
      "local_dns_port": 53,
      "remote_dns_address": "1.1.1.1",
      "remote_dns_port": 53,
      "client_cache_size": 1024,
      "mode": "udp_only",
    }

But it does not seem to respond to DNS requests. Is there any other way to transparently handle DNS requests according to whether it is "local" or "remote"?

It won’t work currently, because in your route table, all packets sent to 10.255.0.1 are routed to the tun interface.

There should be a way to create DNS servers behind the tun interface, which handles TCP UDP packets and bypasses them to the DNS service. If anyone interested, please submit a PR.
