Opnsense Firewall Installation - Virtual Lab Building Series: Ep2

Hey all and welcome to my channel! This is episode 2 of the Cyber Security virtual lab building series where we look at how to install the Opnsense firewall in Virtualbox as well as some basic interface and IP address configurations.

By the end of this video you will have a fully functional lab firewall that you can access via its Web GUI and be ready for the next part of the series where we will install and configure some next generation firewall features.

For those of you finding yourself getting stuck with the virtual networking parts of this lab, I have created a supplementary video explaining how VirtualBox networking modes work, you can check it out here:

Thanks so much, this looks exactly like the step by step guide for a virtual home lab I've been looking for. I'm trying to get started on the GSEC cert and appreciate you sharing your expertise.

This is awesome! I had a couple issues, but nothing a google search couldn't fix. Happy to subscribe. Great pace, too!

The configuration of the Kali and virtual switch is a step that makes alot of people including myself stumble at this tutorial. No doubt more issues lie ahead. Thanks for the video.

Great video, Lyle
Been really educational so far!
For anyone struggling to enable a local and internet connection, you can create a NAT network with the same IP subnet used in the video and you can reach both the internet and the firewall on the same network.

I am a little bit lost at 19:35 You say that we set up a Virtual Switch earlier and therefore this IP comes in play.. Am i missing something? There was never a virtual switch configured

[Don_Ron]

This was a tough install, there are several configurations that must be made not covered but he did put out a disclaimer that there is some assumed knowledge and skill. Great content I'm finally on esp 3 let's get it!!!

[ekhatorcourage]

The process was tough, had to do a lot of research then finally got it😀

[nickstanovic]

I really like the idea of the series. The networking part of it really filters me out from viewing the rest of the videos though. I would assume the network is already going to be configured by a separate networking team and it would be up to the cybersecurity person to use tools to do the monitoring and analyzing or attacking and defending, rather than also setting up network on top of other responsibilities. The VM part was not tough though since someone in security would be doing that often. Anyways I'm happy for the people who understand and that will be able to enjoy the series

[Goodwin]

its crazy how chatgpt does the whole stuff in one script, with a little errors but your idea of this project is perfect, thank you

[scottjmagee]

Excellent video, clear and easy to understand, I'm now subscribed and committed so please continue the good work!

[melmayo]

Super video. Was looking for how to create a host eco system within vbox to practice pfsense. Thanks!

[gadgetbro]

Thank you so much. It's deadly helpful video. please make a video whole detail about OPNsense firewall module their intruduction and best configuration as per this firewall configuration.

[Felix-vehs]

2:20 in my experience, OPNsense will run just fine with 512MB of RAM and 4GB of disk space, but you might run into problems when upgrading to a newer version of when using ressource intense plugins.

Hey all, I have noticed that I get many comments from people running into issues when it comes to manually configuring the OPNSense LAN interface IP address at around 18:50 in the video. If you have issues with this, you can skip this setup and use the OPNSense default address which is 192.168.1.1 to access the OPNSense dashboard. When I created this video I automatically assume that everyone has some basic networking knowledge and is able to configure IP addresses and subnets to device interfaces, and understand concepts like gateway addresses, static IP's, subnetting, switching, DHCP and so on. If you are unsure of these concepts, there are loads of videos on YouTube explaining this, then when you are ready, please do come back and view this video again as you will get more value out of it once the fundamentals of networking are fully understood. Take care! 😊

[didarulislamrifat]

can you please show us the network configuration of Kali please

[nasyaramadhana]

sir. need video to setup virtual switch for home lab. thank you

[stellar]

So, the kali linux and other VM's adapter will be internal network (intnet) so that they can connect with Opnsense. However, when I use ifconfig on my kali linux, it doesn't show the LAN interface of the firewall.

[luisnobregaband]

Hi!! thanks for every video that you did. is very usefull!! i have a question. i install opnsense.. and kali linux. but when i checked on terminal on kali linux with ipconfig, i see another ip adrress.... is that because the ip that you used is just for your network? because i saw that the idea is use a static Ip right? thanks again. !

[JF-zsjm]

Hello LS111, I just did ifconfig in Kali and there is no ip add for eth0
