### Tun Fields
|
||
|
|
|
||
|
|
#### inet4_address
|
||
|
|
|
||
|
|
==Required==
|
||
|
|
|
||
|
|
IPv4 prefix for the tun interface.
|
||
|
|
|
||
|
|
#### inet6_address
|
||
|
|
|
||
|
|
IPv6 prefix for the tun interface.
|
||
|
|
|
||
|
|
#### mtu
|
||
|
|
|
||
|
|
The maximum transmission unit.
|
||
|
|
|
||
|
|
#### auto_route
|
||
|
|
|
||
|
|
Set the default route to the Tun.
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
To avoid traffic loopback, set `route.auto_delect_interface` or `outbound.bind_interface`
|
||
|
|
|
||
|
|
#### hijack_dns
|
||
|
|
|
||
|
|
Hijack TCP/UDP DNS requests to the built-in DNS adapter.
|
||
|
|
|
||
|
|
### Listen Fields
|
||
|
|
|
||
|
|
#### 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.
