Bug Description

Frps部署在Debian 11上
Frpc部署在Arch Linux上
Samba Client使用smbclient（Linux下）与Windows explorer

内网内访问smb一切正常
已经与VPS确认445端口没有被ban
已经确认远程主机没有开启防火墙
已经确认frps加权可以监听1024以下端口。

如果frpc.ini写为

[smb]
type = tcp
local_ip = 127.0.0.1
local_port = 445
remote_port = 445

那么会正常跳出认证会话，但是认证后无法建立连接。

如果修改remote port

[smb]
type = tcp
local_ip = 127.0.0.1
local_port = 445
remote_port = 10445

那么认证成功后可以正常访问smb内文件。

不记得两个月前使用frp有这个issue，近期更新后出现。查阅smb的log一切正常，没有error。
