Use the commands below to provide key information from your environment:
You do NOT have to include this information if this is a FEATURE REQUEST

What version of frp are you using (./frpc -v or ./frps -v)?
0.14.0

What operating system and processor architecture are you using (go env)?
ubuntu 14.04
windows 10 64bit

Configures you used:
服务端配置(frps.ini):
bind_port = 9100
kcp_bind_port = 9101
privilege_token = 654321

客户端配置(frps.ini):
[common]
server_addr = x.x.x.x
server_port = 9100
protocol = kcp
privilege_token = 654321

[vnc]
type = tcp
local_ip = 127.0.0.1
local_port = 5900
remote_port = 5900
use_encryption = true
use_compression = true

Steps to reproduce the issue:
在bind_port 和kcp_bind_port 不一致时（如9100和9101），kcp模式无法连接，
服务端提示：
2017/12/08 12:36:17 [I] [service.go:87] frps tcp listen on 0.0.0.0:9100
2017/12/08 12:36:17 [I] [service.go:96] frps kcp listen on udp 0.0.0.0:9100
2017/12/08 12:36:17 [I] [main.go:112] Start frps success
2017/12/08 12:36:17 [I] [main.go:114] PrivilegeMode is enabled, you should pay more attention to security issues
客户端提示：
2017/12/08 20:40:38 [W] [control.go:483] [f24ba18323dbdd2a] reconnect to server error: i/o timeout

改成相同的端口号后一切正常。

客户端 protocol = kcp 时，server_port 填写服务端 kcp_bind_port 的地址。

感谢指点，但是服务器端输出还是有问题，即使指定了不同的端口，输出里看到的都是tcp端口号。
比如我设置bind_port = 9100；kcp_bind_port = 9101，但是frps运行的输出是2017/12/08 12:36:17 [I] [service.go:87] frps tcp listen on 0.0.0.0:9100
2017/12/08 12:36:17 [I] [service.go:96] frps kcp listen on udp 0.0.0.0:9100

打印错误，实际使用的是你配置的地址，这个下个版本修改下。
