### Listen Fields
#### listen
==Required==
Listen address.
#### listen_port
==Required==
Listen port.
#### tcp_fast_open
Enable tcp fast open for listener.
#### sniff
Enable sniffing.
See [Protocol Sniff](/configuration/route/sniff/) for details.
#### sniff_override_destination
Override the connection destination address with the sniffed domain.
If the domain name is invalid (like tor), this will not work.
#### domain_strategy
One of `prefer_ipv4` `prefer_ipv6` `ipv4_only` `ipv6_only`.
If set, the requested domain name will be resolved to IP before routing.
If `sniff_override_destination` is in effect, its value will be taken as a fallback.
#### udp_timeout
UDP NAT expiration time in seconds, default is 300 (5 minutes).
#### proxy_protocol
Parse [Proxy Protocol](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt) in the connection header.
