centos6.5  2.6.32-431.el6.i686內(nèi)核，ftp 軟件，進行l(wèi)ftp測試操作，操作進行到 輸入密碼后敲命令這 步，產(chǎn)生了 連接不上的 錯誤。

本機機器1 192.168.137.11:測試

[3516] 轉(zhuǎn)到后臺完成傳輸...


我關(guān)閉192.168.137.11的iptables后  機器2鏈接上了 我重新啟動機器1的iptables 重試機器2仍然可以連接  請問大大們原因為何？

同一個問題已經(jīng)在lamp，nfs，ftp的telnet遇到了。。。
我用的是VMware nat模式網(wǎng)絡 是否有關(guān)系呢？

用nat模式，好像不在一個網(wǎng)關(guān)內(nèi)吧，要不換一下橋接的模式。

結(jié)貼：-A INPUT -j REJECT --reject-with icmp-host-prohibited 這條規(guī)則的問題，REJECT 是用來返回一個錯誤的包來回應匹配包，其他的等價于DROP，所以它是一個拒絕TARGET，在規(guī)則的結(jié)束。
