Can anyone help with designing and modeling a website hoster's LAN in Packet Tracer?

Question

Computer networks

Website hosting network. The hoster's network has a web server + file server
+ database server. From the external network, only
the web server is visible to users. Clients see the web server, file server, and database server.
The web server can make requests to the Internet.
There is no access to the Internet from the database server and the file server. Server addresses are static.

I'm not asking you to do it for me.
Can someone explain how to do it?

Answer 1

Arthur Belykh , Everything will not work out. The tracer package cannot imitate a database server, there is only a meager web and ftp.
If the coursework needs to be done in the tracer package, then this means that it will be necessary to work with pieces of iron from cisco.
Your work plan:
1. Draw a diagram, it can be simple, but you can ideally.
2. Divide the network into several parts: Hoster's network, Internet, users. Users are divided into two parts: clients who can do everything and those who have access only to the web.
3. Configure the hardware so that everything works without restrictions (so as not to get confused in the firewall rules)
4. Create rules in the firewall
5. Check if everything works
Here is a sample diagram, you can add or subtract components as you wish.

Answer 2

If you need it right yesterday, then go freelancing. And if you have time and you really want to figure it out, then read the series of articles "Networks for the smallest".

Answer 3

everything is very simple
, the internal network has its own dns namespace. Roughly speaking, when in the connection to the database you write
not localhost
but 192.168.1.3
, the latter can be replaced with a DNS name, say msql_server
Since the name is local in your network, you do not need either ru or uniqueness on the Internet.
actually everything.
Moreover, you can simply make a sub domain,
say mysql1.hoster.ru, and it will have an A record of 192.168.1.4
Naturally, ping on such a domain will only work within that network
