现有机器在dos6.22下工作，只需网络连接同一网段的主机服务器即可，近段时间来经常无故死机，重做系统后也是如此，所以我想达到限制机器与其他机器之间无法网络访问的效果（除开主机服务器，主机服务器是windows系统用了卡巴斯基防火墙），
因此想请教一下，不知是否有什么小程序或软件，可以达到仅允许某一ip或某几个ip对其网络连接，其他统统被拒绝的效果？
该机器用的是dos下的pctcp软件，其中pctcp.ini文件配置一些网络配置，由于我对该软件的不熟悉，所以不知道在其配置文件中是否能有达到该效果的设置。
该pctcp.ini具体内容如下：
[pctcp time]
time-zone-subsection = GMT
[pctcp time GMT]
time-zone-name = GMT
time-zone-full-name = UTC/Greenwich Mean Time
time-zone-offset = 0:00
