# Freedom
|
||
|
||
Freedom is an outbound protocol that can be used to send (normal) TCP or UDP data to any network.
|
||
|
||
## OutboundConfigurationObject
|
||
|
||
```json
|
||
{
|
||
"domainStrategy": "AsIs",
|
||
"redirect": "127.0.0.1:3366",
|
||
"userLevel": 0,
|
||
"fragment": {
|
||
"packets": "tlshello",
|
||
"length": "100-200",
|
||
"interval": "10-20" // ms
|
||
},
|
||
"noises":[
|
||
{
|
||
"type":"base64",
|
||
"packet":"7nQBAAABAAAAAAAABnQtcmluZwZtc2VkZ2UDbmV0AAABAAE=",
|
||
"delay":"10-16"
|
||
},
|
||
{
|
||
"type":"rand",
|
||
"packet":"10-20",
|
||
"delay":"10-16"
|
||
},
|
||
{
|
||
"type":"str",
|
||
"packet":"hiGFW",
|
||
"delay":"10-16"
|
||
}
|
||
],
|
||
"proxyProtocol": 0
|
||
}
|
||
```
|
||
|
||
> `domainStrategy`: "AsIs" | "UseIP" | "UseIPv4" | "UseIPv6"
|
||
|
||
When the destination address is a domain name, configure the corresponding value for Freedom's behavior:
|
||
|
||
- `"AsIs"`: Freedom resolves the domain name using the system DNS server and connects to it.
|
||
- `"UseIP"`, `"UseIPv4"`, and `"UseIPv6"`: Xray resolves the domain name using the built-in [DNS server](../dns.md) and connects to it. The default value is `"AsIs"`.
|
||
|
||
::: tip TIP 1
|
||
When using the `"UseIP"` mode and the `sendThrough` field is specified in the [outbound connection configuration](../outbound.md#outboundobject), Freedom will automatically determine the required IP type, IPv4 or IPv6, based on the value of `sendThrough`.
|
||
:::
|
||
|
||
::: tip TIP 2
|
||
When using the `"UseIPv4"` or `"UseIPv6"` mode, Freedom will only use the corresponding IPv4 or IPv6 address. If `sendThrough` specifies a mismatched local address, the connection will fail.
|
||
:::
|
||
|
||
> `redirect`: address_port
|
||
|
||
Freedom will force all data to be sent to the specified address (instead of the address specified in the inbound).
|
||
|
||
It is a string value, for example: `"127.0.0.1:80"`, `":1234"`.
|
||
|
||
When the address is not specified, such as `":443"`, Freedom will not modify the original destination address. When the port is `0`, such as `"xray.com:0"`, Freedom will not modify the original port.
|
||
|
||
> `userLevel`: number
|
||
|
||
User level. The connection will use the corresponding [local policy](../policy.md#levelpolicyobject) for this user level.
|
||
|
||
The value of `userLevel` corresponds to the value of `level` in the [policy](../policy.md#policyobject). If not specified, the default value is 0.
|
||
|
||
> `fragment`: map
|
||
|
||
A key-value map used to control TCP fragmentation，under some circumstances it can cheat the censor system, like bypass a SNI blacklist.
|
||
|
||
`"packets"`：support two different methods. "1-3" is for segmentation at TCP layer, applying to the beginning 1 to 3 data writes by the client. "tlshello" is for TLS client hello packet fragmentation.
|
||
|
||
`"length"`: length to make the cut
|
||
|
||
`"interval"`: time between fragments（ms）
|
||
|
||
::: warning
|
||
⚠️ "noise":{} is deptecated,only "noises":[{}] is supported in 24.9.16 and later
|
||
:::
|
||
|
||
> `noises`: [ noiseObject ]
|
||
|
||
A Array used to control UDP noise，under some circumstances it can bypass some udp based protocol restrictions.
|
||
xray will loop through this array and send each noise packet one by one
|
||
|
||
`"type"`：Three types are supported. "rand" generates a random byte , "str" uses a user input string, "base64" uses a user input base64 encoded string
|
||
|
||
`"packet"`：If type is set to "rand" this field will take a range "50-100" or a single value "50"
|
||
|
||
if type is set to "str" this field will take a string
|
||
|
||
if type is set to "base64" this field will take a base64 encoded string
|
||
|
||
`"delay"`：delay before sending real data (ms). can be a string range like "10-20" or a single integer
|
||
|
||
If not specified, the default value is 0.
|
||
|
||
> `proxyProtocol`: number
|
||
|
||
The value of `proxyProtocol` represents the PROXY Protocol version. default value is `0`.
