What to set up for a deeper understanding of networks?

Question

FreeBSD

Tell me what you can configure, for example, on freebsd 9 - 11, for a better understanding of how the network works, routing, how two end PCs communicate, DNS, DHCP, TCP / IP, in short, everything connected with the network. I read the axis model, looked at the diagrams, but there is not enough practice for a complete understanding.

Answer 2

Prepare for CCNA with all the practices suggested in the textbook

Answer 3

Routing for two end PCs is practically not configurable.
Raise 2-3 virtual machines in different subnets, raise vpn between subnets, configure end-to-end dhcp from one subnet to another.
But in general, just set up a home router to begin with, so that it normally distributes everything via wifi and wire, close everything superfluous, forward some kind of web server thread to the outside.

Answer 4

I will support Wexter and recommend buying two cheap Mikrotik routers

Answer 5

samba

Answer 6

Tasks for at least 4 virtual machines on FreeBSD (rhombus - 2 gateways, 2 intermediate routers) + 2 terminal "workstations" in opposite "corners" of the network:
Then add a second gateway to one workstation and play around with CARP/VRRP.
