I want to access apache web server running in centos virtualbox. With my laptop connected in office lan network, I can access that webserver with bridged networking mode. But what I want to do is, access it when not connected to any network. Is this possible with virtual interfaces?

The
port forwarding
feature accessible from the Network advanced settings of your virtual machine allows you to selectively expose a port of your virtual machine to your host.This way, you can setup virtual machine port 80/tcp (http traffic) to be easily accessible from your localhost port 8080. Below is an exemple for this setting:
Do the same with port 443/tcp (https traffic) if you serve it as well (ex: 443 -> 8443). Once done, you don't even need to bother with you virtual machine IP address to access its website. Just browse
http://127.0.0.1:8080/
and you are done.Notes:
It is fine to let
Guest IP
blank if it is assigned or known by VirtualBox itslef (I don't think this is the case with bridge mode, so I advise you to chooseNetwork Address Translation (NAT)
,Internal Networking
orHost-Only networking
options. VirtualBox online documentation explain key differences between networking options. NAT will allow your virtual machine to connect the Internet for example, which you might like or dislike.If you clears
Host IP
field, then other computers on you physical network will be able to connect this virtual machine web-server using your host IP address (ex:http://192.168.1.xxx:8080
). This can help you setting up a unique configuration for your both use cases and even improve the security of your virtual machine by not exposing all its open ports to real networks.You can not easily use local port 80 for this forward since ports below 1024 require privileges. Hence the common choice of 8080 in such case.
