症状

客户对网络进行安全扫描时，发现理光MFP机器开启了2049端口，但在机器的Web页中未找到相关的设置。

维修过程

在智能面板与MFP控制器进行通讯时使用了一些端口，同时对外部网络开放，造成进行安全扫描时出现警告。出于安全原因，可以关闭这些端口。

使用的端口包括：

- 111/tcp

- 1022/tcp

- 1023/tcp

- 2049/tcp

- 18315/tcp

- 54080/tcp

- 54443/tcp

- 65000/tcp1

- 65001/tcp1

- 111/udp1,2

- 1022/udp

- 1023/udp

1 这些端口预计在之后的固件中进行修复；

2 端口111/udp 今在以下机型中出现：D219/D220/D214/D196/D236, D259, M0B0/D0A0

要关闭这些端口，需要确认并升级固件；

使用telnet命令关闭端口；

telnet 机器的ip地址；

登录管理员后输入以下命令；

nat_ui port_filter on

nat_ui port_filter_cats off 注：该命令用于关闭18315/tcp端口

logout，输入yes退出系统

同样可以在MFP网页中进行设置。

将以下2项设置为有效。
