Network building possible?

Can I build a network like this so that all devices can access the internet:

Laptop1:

connected via Wi-Fi with smartphone hotspot (has Internet via the smartphone)
Network bridge in Windows, which redirects the connection to the LAN port of Laptop1
Lan Port is Connected to Network Switch

Server (ubuntu server 14.04):

hangs by Lan cable s.Switch

Laptop 2:

hangs by LAN cable s.Switch

Do I have a mistake in the structure? I can't reach the server on the network.

Laptop 2 (Linux) gets internet via the switch and can also be reached in the local network of laptop 1 (could set new LAN connection in Ubuntu, and ipv4 was purchased automatically)

What could it be that I can't reach the server on the network.

Can't install any packages in Ubuntu on the server right now.

This is all a bit too desolate and too complicated.

Connect all devices via network (LAN or WLAN).

Router with modem (and ideally with wi-fi) to the telephone line and the network plug.

All clients and the server get as gateway the IP of the router.

What a circumstance

Why do not you take a router Lte… There's something from TPLink (= about 30 euro), (I'm at home), or the Giga Cube by Vodafone…

Otherwise, the first laptop must pass through the appropriate port to the server and act as a router…

But with laptop 2, the internet also works, with such a network bridge.

But the routing is not… And the outside access to your server.

What do you mean by "not reach the network"?

If you can't even ping the server itself from the laptop 2, then the amount of possible sources of error is already very limited: The switch (port), the cable between the switch and server, the network port of the server or the configuration of the server.

If you can ping the server from both laptops but fail to reach the server services, it may just be because of the configuration of the server.

But if everything goes in the internal network and only from the Internet not (I do not understand your question, but I also like to understand something wrong), then it is probably because of your somewhat complicated construction for Internet access. However, I'm not familiar with the Internet sharing of Windows.

In any case, it is important to search in a structured way for the error and always to look at what works and what does not, and to derive the possible sources of error.

Put simply, the Linux laptop which hangs in the network via LAN has successfully accessed the Internet (from the first laptop)

It must therefore be a wrong configuration of the server, because this does not find the route for the local network or the Internet.

In the graphical interface of Linux laptop which hangs successfully in the LAN, I see an IP address which under the name "default range" is registered (this IP address is the IP address of the LAN haven of laptop 1 (Windows).) This leads the packages then so to speak, to the smartphone, which then takes over the routing for the Internet.

I would need an option to configure the server as well as laptop (Linux). Unfortunately, this one unfortunately has a much newer Ubuntu and of course a graphical interface, and on the server is just an Ubuntu server version.

The routing works. I see that I'm from the laptop which only depends on the LAN switch on the Internet.

The route runs, so to speak, via laptop one and then via the smartphone, which takes over the routing for the Internet

Oh, right now I can't reach the server from any device. (Likewise, I can't reach a device from the server)

Is the LED on the network port from the server?

Does he have an IP address? What say "ip addr" or "ifconfig"?

Is the Eventlog of laptop 1 somewhere that the server gets an address via DHCP or at least tried? What does the syslog on the server say about dhcp or the network adapter?

What does "arp -a" say on laptop 2 after trying to ping the server?

Is it possible if you manually missed the server a fixed IP?

(I just can't say how to check Ethernet L2 connectivity on Linux.) L2ping is probably for Bluetooth only, Anyone?)

It is not too desolate or complicated, but was required.

It works now.

Got it now. It was due to the network card of the server which was configured incorrectly in the config. It works fine now.

But you can configure smartphoneseitig no port release, which again only one solution remains -> Lte use routers.
