Describe the feature request

网络架构
我的电脑 <--> 前置机（公网） --> 指定内网服务器 <--> oracle服务器

指定内网服务器与oracle服务器可以相互访问
前置机对内只能访问指定内网服务器
指定内网服务器不可以访问前置机
前置机仅有特定的很少端口可被其他公网服务电脑访问
前置机（公网），指定内网服务器上运行的 frps frpc 为0.51.2, 下文中的另一公网服务器运行 frps 0.40.0

于是

我在指定内网服务器运行frps, 和frpc, frpc将 oracle服务器的1521及本机的 ssh 通过 stcp向外映射
frps.ini
[common] bind_port = 9000
frpc.ini
`
[ssh]
type = stcp
sk = ssh
local_ip = 127.0.0.1
local_port = 22

[oracle]
type = stcp
sk = oracle
local_ip = 10.20.30.40
local_port = 1521
`

在前置机（公网）上运行两个frpc
frpc1.ini
`
[common]
server_addr = 10.20.30.41
server_port = 9000
tls_enable = false

[sshv]
type = stcp
role = visitor
server_name = ssh
sk = ssh
bind_addr = 127.0.0.1
bind_port = 9001

[ov]
type = stcp
role = visitor
server_name = oracle
sk = oracle
bind_addr = 127.0.0.1
bind_port = 9002
这样将指定内网服务器ssh 及 oracle数据库服务器 1521映射到了前置机上。再通过另一frpc2.ini 将前置机的 22, 9001, 9002向外映射。
[common]
server_addr = x.x.x.x
server_port = 7000
tls_enable = false
log_level = debug
[front]
type = stcp
sk = front
local_ip = 127.0.0.1
local_port = 22
[back]
type = stcp
sk = mssh
local_ip = 127.0.0.1
local_port = 9001

[oracle]
type = stcp
sk = mssh
local_ip = 127.0.0.1
local_port = 9002
结果前置机的 22, 9001 这两个端口能够正常工作，但9002终于无法在外面访问，通过 trace方式看到前置机 frpc2.log 中
2023/08/14 14:27:42 [D] [proxy_wrapper.go:255] [ceae20b5fb455200] [oracle] start a new work connection, ..........
2023/08/14 14:27:42 [D] [proxy.go:201] [ceae20b5fb455200] [oracle] join connections, ......................
2023/08/14 14:27:42 [D] [proxy.go:213] [ceae20b5fb455200] [oracle] join connections closed
`
不知为何会关闭。

求各位大神指导。

我理解的是local_ip是指frpc所在的主机的IP，也就是只能是本机接口。
你这种情况可能需要在本地做个转发才能实现
