[BUG反饋] 防火墻iptables 無(wú)法啟用問(wèn)題

gbnew

我有2臺(tái)VPS，一臺(tái)阿里云的，一臺(tái)香港的，但是2臺(tái)防火墻iptables 全都無(wú)法開(kāi)啟vi /etc/sysconfig/iptables 直接編輯規(guī)則（規(guī)則用的是官方提供的），

自用規(guī)則也不行

反復(fù)測(cè)試iptables -L -n 查看都是空的

重啟防火墻無(wú)效提示規(guī)則錯(cuò)誤
Error occurred at line: 2
Try `iptables-restore -h' or 'iptables-restore --help' for more information.


最后裝了2個(gè)yum模塊可以用了，但是不能再wecp面板里使用。

官方有答案么？我用過(guò)5個(gè)vps wdcp防火墻每一個(gè)能用的，
