华为两台路由器 静态路由
There’s a common misconception that if you have a simple setup, like only one home computer, you don’t need a router. Read on as we explain why even a lone desktop needs a buddy.
常见的误解是，如果您有一个简单的设置(例如只有一台家用计算机)，则不需要路由器。 请继续阅读，以解释为什么即使是一个单独的桌面也需要好友。
Dear How-To Geek,
亲爱的How-To Geek，
A friend helped me move a new desk into my apartment the other day and, while we were putting everything on my new desk, he was surprised I didn’t have a router. I just plug my computer right into the cable modem my ISP gave me.
有一天，一个朋友帮我把一张新桌子搬到我的公寓里，当我们把所有东西都放在我的新桌子上时，他很惊讶我没有路由器。 我只是将计算机直接插入ISP给我的电缆调制解调器中。
It got me thinking, do I need a router? I thought routers were for sharing internet connections and I’m just a guy in a tiny studio apartment with a single desktop computer. My internet works fine and my friend couldn’t explain why he was surprised beyond the fact that he had a router and he thought everyone did. Am I fine or am I missing out on something?
我想，我需要路由器吗？ 我以为路由器是用于共享Internet连接的，而我只是一个小小的一室公寓里只有一台台式机的家伙。 我的互联网运行良好，我的朋友无法解释为什么他除了拥有路由器而且还以为每个人都感到惊讶而感到惊讶。 我很好还是我错过了什么？
Sincerely,
真诚的

As you’ve discovered, you can, in fact, just plug your computer directly into your broadband modem and start browsing the internet. You can also drive a car without insurance or a seat belt too, but that doesn’t mean it’s the best course of action.
正如您所发现的，实际上，您可以将计算机直接插入宽带调制解调器并开始浏览Internet。 您也可以在没有保险或没有安全带的情况下驾驶汽车，但这并不意味着这是最佳选择。
Routers aren’t just for routing data between multiple computers. Let’s take a look at your current setup and the functions provided by your typical home router to highlight why you should get one. We’re going to borrow some diagrams we created for a previous article, HTG Explains: Understanding Routers, Switches, and Network Hardware (which we’d recommend you check out for a more in-depth look at what we’re discussing here).
路由器不仅仅用于在多台计算机之间路由数据。 让我们看一下当前的设置以及典型的家用路由器所提供的功能，以突出说明为什么要购买它。 我们将借用为上一篇文章“ HTG解释：了解路由器，交换机和网络硬件”创建的一些图(建议您查看一下，以更深入地了解此处讨论的内容) 。
Here’s what your simple home network looks like right now:
这是您现在的简单家庭网络的外观：
Your desktop computer is linked directly to the modem which is in turn connected directly to your ISP and the greater internet. From a connectivity standpoint, there’s nothing wrong with this design. Your internet connection will work fine, you’ll be able to browse the web, play games online, etc. From a security standpoint, however, this setup is terrible. Your cable modem is not a security device, it’s a data transfer device.
您的台式计算机直接链接到调制解调器，而调制解调器又直接连接到ISP和更大的Internet。 从连接性的角度来看，此设计没有错。 您的互联网连接将正常工作，您将能够浏览网络，在线玩游戏等。但是，从安全角度来看，此设置很糟糕。 您的电缆调制解调器不是安全设备，而是数据传输设备。
As such, your computer is completely exposed to the internet. This means the IP assigned to your cable modem, your public facing IP address, resolves directly to your home PC. Anything vulnerable on your computer (a port left open, an exploit, a known vulnerability in your OS) is completely accessible to anyone on the internet poking and prodding your public IP. People like to think that they’re anonymous in the sea of IP addresses out there, but there are lots of people who have nothing but time and determination to compromise machines and install malicious software on them (and they use automated tools to poke and prod 24/7).
这样，您的计算机就完全可以访问互联网了。 这意味着分配给电缆调制解调器的IP(面向公众的IP地址)将直接解析为家用PC。 互联网上的任何人都可以完全访问计算机上的任何漏洞(端口保持打开状态，漏洞利用，操作系统中的已知漏洞)，并戳探或刺探您的公共IP。 人们喜欢认为他们在那里的IP地址之海中是匿名的，但是很多人除了时间和决心之外，一无所有就可以危害机器并在其上安装恶意软件(他们使用自动化工具戳戳和生产产品)。 24/7)。
With that in mind, you can see how terrible a direct PC-to-broadband-modem setup is. You’re 100% relying on your computer operating system and any installed firewall software (which is usually pretty cruddy) to protect you from a veritable army of cyber criminals.
考虑到这一点，您可以看到直接的PC到宽带调制解调器设置的糟糕程度。 您100％依靠您的计算机操作系统和任何已安装的防火墙软件(通常非常粗糙)来保护您免受真正的网络犯罪分子的攻击。
In the following diagram we see a home network with a router installed:
在下图中，我们看到安装了路由器的家庭网络：
Even if you have no other devices to put on the network, no laptop, no tablet, no Chromecast, no game console, that router is still a valuable and important element of your network. In addition to providing multi-device routing, routers also include a firewall component that is significantly more sophisticated and stable than the firewall included in Windows (or third-party options).
即使您没有要放在网络上的其他设备，笔记本电脑，平板电脑，Chromecast，游戏机，该路由器仍然是网络中宝贵的要素。 除了提供多设备路由之外，路由器还包括一个防火墙组件，该组件比Windows中包含的防火墙(或第三方选件)更加复杂和稳定。
You could put the most out-of-date computer, riddled with security vulnerabilities, open ports, and easily exploited code behind a modern router and the router’s firewall would stop any attempt at probing the at-risk computer before they posed any threat.
您可以将最陈旧的计算机放置在现代路由器后面，这些计算机上布满了安全漏洞，开放的端口以及容易被利用的代码，而路由器的防火墙将阻止对高风险计算机的任何尝试，直到它们构成任何威胁。
Given that you can pick up a perfectly respectable router for $25 or so, and that your typical router consumes a tiny amount of power (barely more than a bright nightlight), it makes very little sense to not pick one up. Not only will you immediately enjoy improved security but you’ll be ready to add devices to your network without any headaches later.
鉴于您只需花25美元左右就可以买到一台非常受人尊敬的路由器 ，而且典型的路由器消耗的电量很少(几乎比明亮的夜光还多)，所以不去取电几乎没有意义。 您不仅可以立即享受改进的安全性，而且可以随时将设备添加到网络中，而以后再也不会遇到麻烦。
