您认为防火墙的代码是要求某人发布到论坛中的适当方法，这证明，如果需要的话，此任务已经超出您的范围.

That you think the code for a firewall is an appropriate thing to ask someone to post into a forum, is proof, if it''s needed, that this task is beyond you.

初学者，即使对于专家开发人员，您可能也忽略了构建防火墙是一项艰巨的任务.
您应该精通C语言并且对网络编程有深入的了解.

Being a beginner, you possibly ignore that building a firewall is a daunting task, even for an expert developer.
You should master the C language and have a deep knowledge of network programming.
