Help understanding networking


I'm not sure how to label this, so I'll just explain. I have an ubuntu VM running from Vagrant on my laptop. The vagrant ubuntu apache2 has an ip of 10.0.2.15. My laptop is running with 192.168..... If I understand these are two different CIDRs correct? How can I get the 192.168.... to pull up the apache2 server, on 10.0.2.15 in the browser of the ubuntu laptop running on the 192.168....?

Forget cidr.

There are four ways to get networking on common VM's.

One is bridged. (host ip range goes on to client)
Two is NAT. (the virtual ip nic is behind a virtual router) your situation
Three is a VM only network. hope you don't have that, only vm's will talk to each other.
Lastly is no networking.

Generally the host knows that it has a special network and will route traffic correctly to the client even in NAT. However there can be problems all over the setup from permissions to ports.

Many people tend to use Bridged to overcome this.

Usually you can get either Bridged or Nat to work correctly.
