How VirtualBox 7.0 networking works - NAT, NAT Network, Internal Network, Bridged Adapter

[@ls111cyberEd]

This comments section is a little quiet so let me be the first. Are you finding these videos covering these foundational topics interesting, and if so what other foundational IT/cyber security topics are you getting stuck on and want me to cover in future videos? Lets get the conversation started.

[@rmatveev]

This is the best VMs networking explanation so far. Voice explanations and the graphical images are just the right ones for the best understanding of the topic. I'm very appreciate your work!

[@ls111cyberEd]

Thanks for watching, glad it was helpful!

[@waywardson-lw3tx]

This was really, really good. The key point was configuring default gateway of other nodes in the network to firewall's LAN address. This is good.

[@CloudiVist]

Fabulous use of graphics and so well-explained! Liked and subscribed. I wish you every success with your channel.

[@OZTutoh]

I need a Bridged connection! That's all it was. All this time watching other videos being taught to use a Host-only connection with carefully chosen static IP addresses and the firewalls turned off! I can't believe it's working now! Thank you!

[@m.y.7230]

This content is a real gem. Thanks a lot for it!

[@melmayo1090]

SUPER. Exactly Exactly what I needed to test run pfsense without creating a mini network with 1000 Raspberry Pi simulating my devices

[@fodder8062]

Thanks for this video. Helped me out nicely.

[@llamingo]

This video cleared a lot of concepts. Thanks. 👍

[@jadenkelvar5420]

Thank you so much!!! This explanation so much and opens my eyes to understand how to use VirtualBox better.

[@inakigomezvalencia5063]

good shit man. love the simple and straight forward explanations w plenty of diagrams and visual stuff

[@rosler007]

Thank you. The best explanation that I can find.

[@chandrakantjoshi4989]

You cleared my doubt on NAT and Nat Network. Thank you very much.

[@fouednasser9805]

Great explanation.. Really appreciate the good work

[@bobafett2598]

Best explanation ive heard! Thanks!

[@philipparker5291]

This is a really clear explanation. Thanks!

[@jairosantos5821]

Thank You Very Much. Brasil.

[@xen5219]

Incredibly helpful, thank you!

[@ericmoore4515]

Yes, this information is well put together

[@aseilhamid4351]

thanks alot for this amazing explanation

[@mateusjunior1937]

very good series, still waiting for diving in BlueTeam and RedTam series in Deep...keep Going very good tutos and explanation untill now !

[@ls111cyberEd]

Thanks for watching!

[@Niggro07]

This is absolute gold

[@grupo64bits]

Se entiende muy claramente la explicación muchas gracias!

[@ThangNguyen-ul7hn]

Thank you!

[@DomAtWork]

Good Work Sir! Thx a lot.

[@itwing9312]

thanks for your effort sir

[@teclote]

Very helpful, thank you.

[@zedhacking]

bro thank you from my heart

[@lukaszszelag1368]

Good stuff, thanks!

[@henryd4331]

With NAT Network interface enabled, my VMs connect to each other but I can never access the internet. Am I missing something?

[@funnynumber69420]

Make sure "Cable Connected" is checked in network settings and also check the network gateway if that doesnt work

[@henryd4331]

@@funnynumber69420 Thanks for your input! Cable connected is checked indeed.

[@Unitedstatesofamerica-2024]

good teacher

[@bugfixkh]

love this content

[@omarsadek9159]

Provide us with a quick guide on how to setup the intnet network to connect to the WAN through the Firewall. I've tried multiple times to make it work (outbound, port forwarding but nothing is working).

[@Defender2101]

thank you very much

[@remmanemohamed7120]

how did u do the setup of last example ?plz explain how to do it.

[@muhammadnomanilyas5423]

Using virtual networks for years , but didn't observed the concept as you made , explanation was just amazing. How can i connect with you on LinkedIn.

[@ls111cyberEd]

Hi and thanks for watching! I sent you an invite via LinkedIn

[@Thecotilking]

Ok I m subscribing clean explanation, tho I have a current situation that I m trying to resolve now and that’s how I stumbled here. I m using a Free VPN windscribe and i have VMs running Wazuh all bridged network adaptors, now for the VMs to see the change in public IP by the VM I need to be on NAT but being on NAT removes the IPs given to the VMs by the hosts dchp (my router) what do I do to keep the IPs, connectivity between Wazuh components and also ensure the VMs see the VPNs new public IP? 😅

[@amineaitsaidi5919]

Thank's man.

[@HarchaeChopda]

i m pentesting in my lab using (metasploitable) and using NAT network as a network parametre can some tell me if that will be a threat to my host machine (windows)

[@GuyFawkes1]

Can this explanation be used for VMWare as well? or it works slightly different?

[@ls111cyberEd]

Thanks for watching, there is a slight difference, yes, but the underlying networking concepts are basically the same.

[@martinlastname8548]

My host device is windows 11. I have a VPN that allows me to connect to internal infrastructure that is not open to the public. I have a Kali in my VM machine with the network set bridges adapter. The problem is I cannot tested or connect to internal infrastructure to test the security of servers etc. is there a way around this?

[@jackwilson4863]

In NAT mode, does each virtual NAT device get a unique ip address on the external interface from the physical network? And if so would the vms be able to reach each other via port forwarding, with traffic going out the host to the physical network, then back into the host?

[@ls111cyberEd]

Hi, thanks for watching, no, when you use port forwarding in NAT mode the external address is your host's (physical computer) IP address. If you have one of your VM you want to make accessible to both your physical network and virtual network you can setup port forwarding on it and access the service on the host physical IP + the port you mapped, however, if you have more than one VM you wish to host services on while in NAT mode, I suspect you will run into issues because NAT mode by default always gives the guest VM an IP of 10.0.2.5 so VirtualBox won't know which VM you are mapping/forwarding to if all of them use 10.0.2.5 if that makes sense, unless you manually assign a different IP to each VM. Personally, I think to make this less cumbersome you should consider using either a bridged network mode or putting all your VMs that need to communicate with one another into a NAT Network mode or Internal network. Hopefully, this helps.

[@cyb3ersounds]

Please. I have VB and VM. I have virtual machines on VMware and my Kali on Virtual box. I want all of them to communicate with each other. What settings do I make use of.

[@mehribankrimova2964]

you can either use Nat network, or bridged network

[@yourlabpartner]

i am unable to ping kali (192.168.1.10/24) and opnsense (192.168.1.254/24) on virtualbox ...both are on the same network (inet), when i ping opnsense from kali, following is the reply message. From 192.168.1.10 icmp_seq=125 Destination Host Unreachable

[@mariomanningfan]

same reason I came to this video tonight. did you find a solution? the only thing that is working for me is switching all my VMs to the bridge. But I do not want my VMs in communication with my actual machine.
