UDP 27015端口，看来你也是转发cs2的（

遇到了同样的问题

frps.toml:

bindPort = 7000

webServer.addr = "0.0.0.0"
webServer.port = 7500
webServer.user = "admin"
webServer.password = ""

frpc.toml:

serverAddr = "****.****.****.****"
serverPort = 7000

webServer.addr = "127.0.0.1"
webServer.port = 7400
webServer.user = "admin"
webServer.password = ""

[[proxies]]
name = "cs2"
type = "udp"
localIP = "127.0.0.1"
localPort = 27015
remotePort = 6000

客户端和服务端都没有任何报错，却没有流量被转发

不知道为啥，老版本（非go版本）就能转发。
