Bug Description

配置了stcp和sudp 然后远程连接，但是只走tcp

frpc Version

0.61.2

frps Version

0.61.2

System Architecture

linux/amd64, windows/amd64

Configurations

这是frps.toml

bindPort = 7000
auth.method = "token"
auth.token = "*"
log.to = "./frps.log"
log.level = "info"
log.maxDays = 3
transport.maxPoolCount = 2

这是frpc.toml

serverAddr = "*"
serverPort = 7000
auth.method = "token"
auth.token = "*"
loginFailExit = false

[[proxies]]
name = "stcp_rdp"
type = "stcp"
localPort = 3389
localIP = "127.0.0.1"
secretKey = "*"
transport.useCompression = true

[[proxies]]
name = "sudp_rdp"
type = "sudp"
localPort = 3389
localIP = "127.0.0.1"
secretKey = "*"
transport.useCompression = true

[[proxies]]
name = "xtcp_rdp"
type = "xtcp"
localPort = 3389
localIP = "127.0.0.1"
secretKey = "*"
transport.useCompression = true

这是visitor frpc.toml

serverAddr = "*"
serverPort = 7000
auth.method = "token"
auth.token = "*"
loginFailExit = false

[[visitors]]
name = "stcp-rdp-visitor"
type = "stcp"
serverName = "stcp_rdp"
secretKey = "*"
bindAddr = "127.0.0.1"
bindPort = -1
transport.useCompression = true

[[visitors]]
name = "sudp-rdp-visitor"
type = "sudp"
serverName = "sudp_rdp"
secretKey = "*"
bindAddr = "127.0.0.1"
bindPort = 23389
transport.useCompression = true

[[visitors]]
name = "xtcp-rdp-visitor"
type = "xtcp"
serverName = "xtcp_rdp"
secretKey = "*"
bindAddr = "127.0.0.1"
bindPort = 23389
transport.useCompression = true
keepTunnelOpen = true
fallbackTo = "stcp-rdp-visitor"
fallbackTimeoutMs = 2000

我想在xtcp连接失败后fallbackto stcp连接，但是这样走的是tcp，我以为是xtcp的问题后来我去掉xtcp只尝试stcp和sudp并设置同一端口，走的还是tcp协议

貌似是这样的，我用stcp也测了，sudp无效。
不过rdp用stcp配合quic也用起来挺快（比我开启了udp的vpn要快）

你是怎么配置的，方便分享一下嘛，我在服务端添加了quic协议端口quicBindPort = 7000，在客户端添加了transport.protocol = "quic"，直接连不上frp了

因此怀疑 frps 所在网络，没有接受 UDP

你说的对，我忘记了打开阿里云安全组，谢谢你 @xqzr
