服务器端开启特权模式

# frps.ini
[common]
bind_addr = 0.0.0.0
bind_port = 7500
vhost_http_port = 801
vhost_https_port = 443
dashboard_port = 7000
log_file = ./frps.log
log_level = info
log_max_days = 3
privilege_token is correct
privilege_mode = true
privilege_token = oxcm!Jkn/jQ(S?of
privilege_allow_ports = 2000-3000,3001,3003,4000-50000
max_pool_count = 100

客户端

# frpc.ini
[privilege_web1]
privilege_mode = true
type = http
local_ip = 127.0.0.1
local_port = 30000
use_gzip = true
use_encryption = true
custom_domains = xx.xxxx.xx

之后打开xx.xxxx.xx:801，frps就会自动退出，并且报错，错误内容如下
