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)?
0.30.0
0.30.0

What operating system and processor architecture are you using (go env)?
server: centos 7 amd64
client:windows 10 amd64

Configures you used:
frps.ini

[common]
bind_port = 7000
allow_ports = 2000,2004
token = frp1234
tcp_mux = true

frpc.ini

[common]
server_addr = server ip
server_port = 7000
token = frp1234


[ssh]
type = tcp
local_ip = 127.0.0.1
local_port = 22
remote_port = 2000

Steps to reproduce the issue:
1../frps -c frps.ini
2../frpc -c frpc.ini

Describe the results you received:
Client:

2019/12/07 00:33:37 [W] [service.go:97] login to server failed: dial tcp server ip:7000: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
dial tcp 111.231.163.134:7000: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Server

2019/12/07 00:26:59 [I] [service.go:141] frps tcp listen on 0.0.0.0:7000
2019/12/07 00:26:59 [I] [root.go:205] start frps success

Describe the results you expected:
客户端能连上服务器端

Additional information you deem important (e.g. issue happens only occasionally):
我能在服务器上成功用上述客户端配置启动客户端（server_addr用的是link addr），启动frpc
并能成功用端口2000连上ssh

Can you point out what caused this issue (optional)
No

服务器上开了7000端口和2000，2004端口，服务器上nc -l 2000，客户端用nmap扫端口能看到端口2000是open
但端口7000一直是filter
