SDN can actually create a private virtual network for the VMs to communicate between each other without having to deal with vlans on the physical switch, router or firewall. Good example would be mysql on one VM while another VM or CT run the web server. The traffic stays on that SDN network unless you turn on SNAT. The VM running the web server you just add another network interface to it to allow public traffic. So there are alot of crazy things you can do with SDN.
wait, so can you implement a client vpn now - so a group of VMs or CT all work under that vpn now? Basically, no need for something like pfsense or other firewalls to manage all that?
I wounder if there would be any benefit using SDN for doing nfs between a visualised nas and other VMs In my uses case i have trueNAS visualised, and uses nfs for my persistent docker volumes. Which are running in another VM on the same host.
So is sdn networking in proxmox the equivalent to, (in essence) 2 cascading routers where the cascaded router is an independent network and it can ping everything internationally and externally to it, but not the first router, cannot ping anything behind the cascading Router?
Sorry, I installed 8.0.3, gave it a week on an i3/32GB/1TB with a 14TB NAS, and I just could not get it to work as nicely as my VBox on the same hardware (on a Debian base). My resource allocation was easier, my VMs easier to install, my templates easier to build and manage on VBox. For containers, I have a debian docker template that I can spin up if I want it separate, or an always on debian docker VM. Speed to clone is a lot faster to either the on board 1TB or to the NAS than what Proxmox was able to do. Please keep these type videos coming, but wanted to let you know that Proxmox doesn't work for everyone.
@@NovaspiritTech I use remotebox. I have, in my homelab a Ryzen 7/64GB/14TB on debian 12 host with a VBox 6.1.x setup.

I have a couple of Lenovo M73 TFF pcs (one is my management machine) that I can run various iron systems, like vmware/esxi and tested proxmox on, along with an i5 ideapad 36GB/1TB laptop (to make a mobile management machine) not to mention the dozen+ RPis running around doing various functionality, including a Ham Digipeater. I was just unable to get Proxmox to do what I wanted prior to the possibility of moving it over to the the Ryzen 7 box. Your channel was great, but now that you seem to be a proxmox 'fanboi', I have to reconsider subscribing. You used to cover a lot of interesting subjects, but out of the last 8 videos, 6 were Proxmox. 1 was a RISV-V review, and one was a competitor to proxmox, apparently with you having the same issues with it that I have with Proxmox...
Last year when I looked into upgrading I only had 3 nodes as test VM clusters so I found it easier to just wipe everything and install a new 8.0 version.😅
I'm thinking this is for a large datacenters to separate vendors that need their own network separation and within their own network their own firewall and internal network so VXLAN perhaps, not sure
Why don't you say that if you connect these two LXC containers to the same network on different Proxmox nodes in the same cluster, then these machines will not be able to ping each other? As if they were on different subnets. I spent a lot of time experimenting to understand this.
Can you disable your internal access ? i mean , can you deny access to your local address ? Maybe this is useful if you have one container and a secondary with a db.
I tried to do a fresh install of Proxmox 8.1, but two separate systems can't boot from USB. the USB was created with Rufus and balenaEtcher to the same negative result. Did anyone else had the same problem
Agreed. Proxmox is cool but the FC nic support is very poor. So I had to go with VMware for my 10gb setup. Hence, this is not really something I am interested in

Great info! Just followed along on my test server and went exactly as planned!
I love the proxmox series learning hella stuff
This is what i was looking for. I'am also gonna do the upgrade !
Thnx !

In my uses case i have trueNAS visualised, and uses nfs for my persistent docker volumes. Which are running in another VM on the same host.

Thanks for this. Much appreciated

yea, vbox is lots of fun and very useful expsially if you install phpvirtualbox to help manage it

How about a similar tutorial but applied to a 3 node cluster?
Thanks Don.

I hope you can do a sdn cross datacenter. Setup two proxmox datacenter/cluster, and connect it together with evpn.
Another good tutorial. I am learning about it, love the proxmox videos.thanks

if you setup vlan aware and use the same vlan number between the two containers then yes
"Not so simple". Next: Don makes the whole process look simple 😅

Thank you for sharing. I already have it set-up and it's really useful 👌
I didn't have to do any of this when upgrading, I just ran the updates and I have SDN...
Same here but i suspect w/o the packages it won't work very well. :)
What is SDN lol. I know I should google it...
It’s amazing especially with p4 crazy switching speeds are possible
Since this is now exclusively a proxmox channel i have to unsubscribe. Bummer, the other stuff was good but this is not something i need

Dang ungreed it’s something I need so I subscribed and the other seemed like useless diy projects for boredom
Bye dummies!!!
Not an airport. No need to announce your departure.
