我正在开发一个分布式应用程序，我目前正在 LAN 上的 Ubuntu VM 集群上运行该应用程序。我想评估我的应用程序在 WAN 上的性能。所以我决定用Netem和tc来增加网络延迟等。。我的问题是我不知道要为延迟、抖动、丢包等设置哪些值，这代表了一个通用的 WAN，用于创建有意义的评估结果，支持我声称应用程序已通过 WAN 进行评估的说法？到目前为止，我还没有找到一个资源表明，将我转发到这样的资源也是非常受欢迎的。非常感谢。
我有一个在 Windows Server 2019 上运行的 Hyper V 虚拟机，它将用于运行来宾操作系统（Windows 10）。如何允许访问 Internet，但阻止它访问 LAN、网络共享文件夹、打印机等。
我想建立一个允许我拥有“浮动IP”的系统。为此，我想拥有一个具有 5 个 IP 地址的服务器。然后它将该流量中继到另一台（或更多）包含 4 个 VPS 的机器。这第二台机器只有一个真实 IP 地址，但我希望每个 VPS 都有一个专用 IP。服务器 1 将位于数据中心，服务器 2 将位于另一个数据中心。但是我无法在服务器2上获得多个IP，所以我必须模拟它。此外，我稍后可以将服务器 2 移动到不同的数据中心，并且我的 IP 可以毫无问题地转发到服务器 2 的新 IP。
两台计算机将位于不同的位置，所以我不能将它们组合在一起。我需要通过互联网将流量从一个隧道传输到另一个。
我对网络的了解还不够，无法无缝转发所有流量。我从哪里开始学习才能弄清楚？另外，如果您对我需要做什么有任何想法，我将不胜感激。我已经搜索了互联网，它是如此压倒性，我只是想在这里问有人可以指出我正确的方向。
5IP ========>服务器1 ====5IP===>服务器2
在图中，ISP 将流量从 5 个 ips 引导到 Server1。Server2 从 Server1 获取流量，但它应该认为它从 Internet 获取流量。
我正在考虑的一个大问题是我希望它转发所有流量，而不仅仅是 TCP。我只是不知道如何开始。谢谢你。
嗨，我对我的一个公共 IP 的跟踪路由有奇怪的行为在一行中，我有多个主机名，其时序如下例所示，在第 5 行

有没有人见过这样的东西？这是什么意思？
非常感谢您的回答。米
我在一栋商业大楼的一楼有一家小企业。我们也打算租这栋楼的4楼，所以我需要把我们的网络扩展到4楼。
目前，在一楼，我有一个 UniFi Switch PRO 48 PoE（在 UniFi 安全网关后面）。
我可以为 4F 办公室购买另一个交换机并使用 SPF 模块桥接这些交换机吗？
https://store.ui.com/collections/operator-accessories/products/sfp-modules?variant=31221652109
以前从来没有这样做过。. . 所以不确定是否还有其他我应该注意的注意事项，或任何未知的未知数。
干杯，
我们有两个办公室，每个办公室都有一台服务器，我们希望每个办公室的所有相关人员都能访问每个办公室的工作。
我无法访问我这边的路由器，因为它是我们大楼内所有与我们无关的办公室之间的公用路由器。
在我的办公室中，我安装了 Synology NAS，我认为它是另一个办公室中的 Windows 服务器，但我可以确定。
我们的工作人员可以访问 Synology NAS 上的作业，该工作目前正在与 google 驱动器同步，但这会导致问题，因为工作人员还通过个人 PC 上的驱动器应用程序链接到 google 驱动器，并且它正在比较和同步所有时间，我认为正在重复，即文件名（1）正在出现。
我们可以使用 VPN 或其他方式在两台服务器之间创建链接，还是应该选择云选项？目前它是谷歌驱动器，但亚马逊或其他东西会更好吗？
我的 ASA 有问题。我在 ASA 中设置了多个 WAN 和静态 NAT。我可以通过特定端口从这些 WAN 地址连接到我的服务器，但我遇到了互联网连接问题。我无法从该服务器浏览到外部。我错过了什么？

我们正在考虑集中我们的 RADIUS 基础设施，但我找不到任何有关身份验证器（即交换机或 WLC）和身份验证服务器之间可接受延迟的信息。
100ms 的往返会不会出现问题，那么 200ms 呢？
我有来自 ISP 的 Internet 连接，并获得了 8 个 IP 和 5 个有用 IP 的静态 IP 池...
现在我想建立以下网络
ISP -> Mikrotik 路由器 -> 交换机 ===> Web 服务器和 LAN
现在我的 Web 服务器使用所有四个 IP，一个 Live IP 将在 Mikrotik 路由器中配置。
我的问题是使所有服务器都可以通过分配的静态公共 IP 访问并且还希望使用带有私有 IP 的 LAN 的正确方法是什么。
我应该使用 NAT、PAT 或 PORT 转发还是有任何其他更好的技术以及如何去做..
我在一家小公司工作，我们使用ASUS RT-N18U设置了 LAN 。我们在一个小型办公室中，作为商业园的一部分，我们的网络通过有线网络进入，作为商业园提供的一揽子服务的一部分。
昨天我们停电了，从那以后我们就不能上网了。我可以连接到我们的本地服务器、打印机等，仅此而已。我不知道问题是什么，但是如果我什至可以知道问题是我们的 LAN 内部还是外部问题，那将是一个开始
编辑：我无法从路由器控制台 ping 谷歌（或任何其他）服务器。
