Final actions
route
{
"action": "route", // default
"outbound": "",
... // route-options Fields
}
!!! note ""
You can ignore the JSON Array [] tag when the content is only one item
route inherits the classic rule behavior of routing connection to the specified outbound.
outbound
==Required==
Tag of target outbound.
route-options Fields
See route-options fields below.
route-options
{
"action": "route-options",
"override_address": "",
"override_port": 0,
"network_strategy": "",
"fallback_delay": "",
"udp_disable_domain_unmapping": false,
"udp_connect": false,
"udp_timeout": ""
}
route-options set options for routing.
override_address
Override the connection destination address.
override_port
Override the connection destination port.
network_strategy
See Dial Fields for details.
Only take effect if outbound is direct without outbound.bind_interface,
outbound.inet4_bind_address and outbound.inet6_bind_address set.
network_type
See Dial Fields for details.
fallback_network_type
See Dial Fields for details.
fallback_delay
See Dial Fields for details.
udp_disable_domain_unmapping
If enabled, for UDP proxy requests addressed to a domain, the original packet address will be sent in the response instead of the mapped domain.
This option is used for compatibility with clients that do not support receiving UDP packets with domain addresses, such as Surge.
udp_connect
If enabled, attempts to connect UDP connection to the destination instead of listen.
udp_timeout
Timeout for UDP connections.
Setting a larger value than the UDP timeout in inbounds will have no effect.
Default value for protocol sniffed connections:
| Timeout | Protocol |
|---|---|
10s |
dns, ntp, stun |
30s |
quic, dtls |
If no protocol is sniffed, the following ports will be recognized as protocols by default:
| Port | Protocol |
|---|---|
| 53 | dns |
| 123 | ntp |
| 443 | quic |
| 3478 | stun |
reject
{
"action": "reject",
"method": "default", // default
"no_drop": false
}
reject reject connections
The specified method is used for reject tun connections if sniff action has not been performed yet.
For non-tun connections and already established connections, will just be closed.
method
default: Reply with TCP RST for TCP connections, and ICMP port unreachable for UDP packets.drop: Drop packets.
no_drop
If not enabled, method will be temporarily overwritten to drop after 50 triggers in 30s.
Not available when method is set to drop.
hijack-dns
{
"action": "hijack-dns"
}
hijack-dns hijack DNS requests to the sing-box DNS module.
Non-final actions
sniff
{
"action": "sniff",
"sniffer": [],
"timeout": ""
}
sniff performs protocol sniffing on connections.
For deprecated inbound.sniff options, it is considered to sniff() performed before routing.
sniffer
Enabled sniffers.
All sniffers enabled by default.
Available protocol values an be found on in Protocol Sniff
timeout
Timeout for sniffing.
300ms is used by default.
resolve
{
"action": "resolve",
"strategy": "",
"server": ""
}
resolve resolve request destination from domain to IP addresses.
strategy
DNS resolution strategy, available values are: prefer_ipv4, prefer_ipv6, ipv4_only, ipv6_only.
dns.strategy will be used by default.
server
Specifies DNS server tag to use instead of selecting through DNS routing.
