现在组成方案：二级域名(外网ip)+路由器(lede)+frp

一键脚本安装

https://github.com/MvsCode/frp-onekey

https://github.com/fatedier/frp/blob/master/README_zh.md

(服务器安装路径/usr/local/frps) 服务器配置文件frps.ini 如下：

# [common] is integral section
[common]
# A literal address or host name for IPv6 must be enclosed
# in square brackets, as in "[::1]:80", "[ipv6-host]:http" or "[ipv6-host%zone]:80"
bind_addr = 0.0.0.0
bind_port = 5443
# udp port used for kcp protocol, it can be same with 'bind_port'
# if not set, kcp is disabled in frps
kcp_bind_port = 5443
# if you want to configure or reload frps by dashboard, dashboard_port must be set
dashboard_port = 6443
# dashboard assets directory(only for debug mode)
dashboard_user = user
dashboard_pwd = mima
# assets_dir = ./static

# 设置域名（保证此域名可用）
subdomain_host = frp.domains.com

vhost_http_port = 81
vhost_https_port = 4433
# console or real logFile path like ./frps.log
log_file = ./frps.log
# debug, info, warn, error
log_level = info
log_max_days = 7
# privilege mode is the only supported mode since v0.10.0
privilege_token = tokenxxx
# only allow frpc to bind ports you list, if you set nothing, there won't be any limit
#privilege_allow_ports = 1-65535
# pool_count in each proxy will change to max_pool_count if they exceed the maximum value
max_pool_count = 50
# if tcp stream multiplexing is used, default is true
tcp_mux = true

以上配置的对应在路由器上OpenWrt R7.5.5 By Lean客户端 Global Setting如下：

Server：frp.domains.com
端口：5443
Privilege Token：tokenxxx 
HTTP穿透服务端口：81
HTTPS穿透服务端口：4433
服务注册间隔：50

上面服务器配置对应在路由器文件路径:/var/etc/frp(进SSH) frpc.conf

[common]
server_addr=frp.domains.com
server_port=5443
privilege_token=tokenxxx
log_level=info
log_max_days=3
protocol=tcp
log_file=/var/etc/frp/frpc.log
tcp_mux=true
login_fail_exit=false

[frp]
type=http
custom_domains=xx.domains.com
local_ip=192.168.1.1
local_port=80
use_encryption=true
use_compression=true

以上[frp]为一个frp服务列表type=http(https作者还没解决，有点问题，可以nginx代理即可)

frp https 服务

访问web

web frp控制台

根据服务器配置信息如下：

dashboard_port = 6443
dashboard_user = user
dashboard_pwd = mima

即是frp.domains.com:6443 账号user密码mima,进入web控制台

https处理：

在frp.domains.com.conf配置文件上设置代理：

map $http_x_forwarded_for $clientRealip {
   "" $remote_addr;
   ~^(?P<firstAddr>[0-9\.]+),?.*$  $firstAddr;
}
server {
  listen 80;
  listen 443 ssl http2;
...
location / {
           proxy_pass http://127.0.0.1:6443;  #此处的6443就是你安装frp时设置的dashboard_port端口
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $clientRealip;  # $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       }
...

即可使用https://frp.domains.com访问

外网访问内网

根据配置信息如下
服务器上配置信息

...
vhost_http_port = 81
...

客户端配置信息

[frp]
    type=http
    custom_domains=xx.domains.com
    local_ip=192.168.1.1
    local_port=80
    use_encryption=true
    use_compression=true

这里使用的是http,因为作者似乎还没解决https 502问题
http访问：xx.domains.com:81即可

https处理：

在xx.domains.com.conf配置文件上设置代理：

map $http_x_forwarded_for $clientRealip {
   "" $remote_addr;
   ~^(?P<firstAddr>[0-9\.]+),?.*$  $firstAddr;
}
server {
  listen 80;
  listen 443 ssl http2;
...
  location / {
           proxy_pass http://127.0.0.1:81;  #此处的,81(4433)就是你安装frp时设置的vhost_http(s)_port端口
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $clientRealip;  # $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       }
...

即可使用https://xx.domains.com访问192.168.1.1
