Administering two subnets?

Question

System administration

Hello, there are two networks 1) Internet access 2) Promed program. To work in them, you need to physically switch the wires. Is it possible, for example, to connect a wire to the switch from the Internet and from the promed and already from the switch to the PC?

Answer 1

It is possible and impossible.
Yes, because it is technically possible to do so.
It is impossible - because without knowing all the intricacies of one and the other network, you can disrupt the normal operation of all users in the enterprise. Each network can have its own DHCP; then, networking through a switch will create complete chaos in issuing addresses.
Bottom line: this should be done by a system administrator who understands what he is doing, and not just randomly plugs cables into the switch.

Answer 2

It's probably not just done. And it is possible that your actions fall under the dismissal at best, and at worst under the Civil Code and the Criminal Code.
Technically, it is solved either with two network cards, or a switch with vlan, or a router.

Answer 3

Plug in a second network card in PeKa and that's it. Unless of course there is not one subnet.

Answer 4

You better not :) Because the evil admin will come running :)
