Create a virtual router to provide Internet access to a virtual LAN

In this tutorial, I’ll be talking about connecting a virtual LAN network created using VirtualBox to a physical LAN segment with Internet access. The reason for this tutorial is to demonstrate that it is possible to create a virtual environment that closely mimics a production company LAN network in functionality. This includes being able to run services such as DHCP and DNS on your virtual LAN environment and using a router to provide access to the Internet.

My virtual LAN is setup as follows:

  • Network: 10.0.0.0/8
  • Router/Gateway: 10.0.0.1 (this is the device we’ll be configuring in this tutorial)
  • DNS: 10.0.0.100 (my active directory domain controller named dc.dyndns.local)
  • DNS suffix: dyndns.local

My physical LAN is setup as follows:

  • Network: 192.168.1.1/24
  • Router/Gateway: 192.168.1.1 (a verizon router)
  • DNS: 192.168.1.1 (same verizon router)
  • My computer (virtual machine host): 192.168.1.4 (via dhcp from the verizon router)

    Hi, I know this is an old article/video, but I just followed it with succes, thanks.
    I have one question:
    Will the router interfere with clients on my host network? What I mean is, are there any riscs using this method, so that the clients on my host network will pickup this pfSense router as gateway instead of the default gateway?

    TIA

    nimmer
