`tproxy` inbound is a linux TProxy server.
### Structure
```json
{
"inbounds": [
{
"type": "tproxy",
"tag": "tproxy-in",
"listen": "::",
"listen_port": 5353,
"sniff": false,
"sniff_override_destination": false,
"domain_strategy": "prefer_ipv6",
"udp_timeout": 300,
"network": "udp"
}
]
}
```
### Listen Fields
#### listen
==Required==
Listen address.
#### listen_port
==Required==
Listen port.
#### sniff
Enable sniffing.
Reads domain names for routing, supports HTTP TLS for TCP, QUIC for UDP.
This does not break zero copy, like splice.
#### 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).
### TProxy Fields
#### network
Listen network, one of `tcp` `udp`.
Both if empty.
