Original GitHub issue: https://github.com/fatedier/frp/issues/1680

客户端配置:
type = udp
local_ip = 127.0.0.1
remote_port = 27015
local_port = 27015

服务器与客户端均没有开启ipv6
服务器端使用netstat -ano查看只有UDP6 :::27015没有UDP 0.0.0.0:27015

服务端也遇到这个问题，换过端口，都起作用
只能监听ipv6的，ipv4的没有，导致客户端连不上服务端
[root@linux_amd64]# netstat -nap | grep 56000
tcp6 0 0 :::56000 :::* LISTEN 18652/./frps
[root@linux_amd64]# cat frps.ini
[common]
bind_port = 56000

使用release中的v0.32.0和v0.21.0都是这样，其他版本没试过
在两种环境中试过：
1.
