网络系统 帮助: 如何将外部请求按东道国名向内部自行提出?
原标题:Network Systems Help: How to route an external request, by hostname to an internal ip?

欢迎我第一个关于流.的问题。

我仔细研究,我没有发现这个问题。 然而,这可能是因为我不知道如何问我需要回答的问题。

www.un.org/spanish/ecosoc 资料:

I m a programmer who left the public sector that had a, surprisingly, well-managed IT department that had all this crap working for me. I now work for a private company that needs a bit of network systems help.

我们:

  • A SQL Server
  • An Application Server
  • A File Server
  • A Web Server
    • multiple web services
    • team foundation server
    • share point services
  • 5 desktops

我们的内部网络。

We also have: - No domain controller - No Internal DNS / NAT / DHCP Server.

我们目前正在使用一条路子,用于人运和港口转运。 我们今天正在获得一个固定的IP。

www.un.org/spanish/ecosoc 问题:<>

我需要做些什么来把我们的外部领域/子域放在我们新的静态IP上,并且这些要求(通过使用的东道名称)会打到一个特定的服务器?

目前的配置(港务)

ourdomain.com:1234 -> router/port-forwarding -> SQL Server:1433
ourdomain.com:1235 -> router/port-forwarding ->  Web Service 1:8081
ourdomain.com:1236 -> router/port-forwarding ->  Web Service 2:8082
ourdomain.com:1237 -> router/port-forwarding ->  Application Server:5410

我想:

sql.ourdomain.com:80  -> ??? -> SQL Server:1433
svc1.ourdomain.com:80 -> ??? -> Web Service 1:80 (host: svc1.ourdomain.com)
svc2.ourdomain.com:80 -> ??? -> Web Service 2:80 (host: svc2.ourdomain.com)
app.ourdomain.com:80  -> ??? -> Application Server:5410

(东道主:xxx)是我将在国际空间法学会网站组合中指明东道方之处。

在有些情况下,港口收费是必要的,但并非每一种情况都是理想的。 我想记住有意义的名称,而不是任意的港口号码。

如果我在这里要求的话是完全荒谬的,那么,要看的话就好了。 我只想看某些方向。

感谢!

让我澄清几点。

  1. We only have a single static public IP address.
  2. Assume that we can acquire / setup the necessary hardware / software to achieve this.

如果说我们需要购买某些企业层次的路由硬件,那就只是它所需要的。 我知道这一点是可能的,因为在我的上一份工作中,我们共有40或50个领域,它们都指出,在内部网络内,曾经向不同的服务器开过路。 或者说,至少这是我最了解的情况。

我今天实际上称呼他们,并问他们,但主编却开了。

我真心要推动我们刚刚摆脱云层,因为没有人想要雇用网络工程师或系统分析员,更不用说建立一个数据中心。

最佳回答

如果每个次主题都决心进入不同的公共范围,那么这项工作就容易进行(例如,如果贵国的国家安全局被配置成<条码>sql.ourdomain.com)。 页: 1

sql.ourdomain.com  IN A 1.1.1.1
svc1.ourdomain.com IN A 1.1.1.2

你的路由人只能根据在包裹内所含有限信息作出决定。 通常,路由人可以看望管道或港口信息。 如果您的航道与港口转运混在一起,则路由人看港口号,并利用港口处理翻译决定。

rule: incoming port 1000, forward to 192.168.1.100:1433
rule: incoming port 1001, forward to 192.168.1.101:80

但是,如果港口相同,路由人需要其他信息来决定如何进行翻译。 多数低端路人(例如Cisco ASA系列、Juniper SRX系列)可以利用Pi作出翻译决定。 倒数是,你需要从您的ISP购买多端地址。

rule: incoming ip 1.1.1.1, forward to 192.168.1.100:1443
rule: incoming ip 1.1.1.2, forward to 192.168.1.101:80

IIS, which operates on a much higher layer on the network stack, can make this differentiation by looking at the HTTP headers. This works for multiplexing a single ip and single port to multiple websites. In this case, since SQL and your web server speak different protocols, you won t be able to leverage this.

您可能想考虑的另一个技术是,如果你的装置支持IP秘密通道,IPsec隧道。 倒数是,你们的同事(我假定他们正在使用这一方法)需要完成更多的配置。
