Proxmox WIFI interface in bridge

[kekosz]

Hi!
Is it possible to put the wifi interface into the bridge? Ye, I know it`s not the best solution but i cannot use a ethernet cable.

You can but your guests won't be able to access the internet or other hosts on the LAN. You would need to setup a NAT configuraton, NATing between the bridge and the wifi interface. See the wiki: https://pve.proxmox.com/wiki/WLAN

So should I set up wifi interface as normal and leave bridge as empty? Then configure NAT?

Two more question to you bro. The virtual machines will not get addresses from my core router sure? And the second one... will I have access to stuff on VM from out of proxmox?

Your router won't see any VMs. All it will see is the PVE host which acts as another router doing the NAT between your LAN and another private subnet you use for your VMs. This is needed as the Wifi AP will drop all packets that doesn't come from the PVE host itself (MAC of the Wifi interace). So the PVE host has to act as a man-in-the-middle between your Wifi AP and your VMs.

will I have access to stuff on VM from out of proxmox?

If you set up some port-forward yes.

Okay. I tested and everything works. But If i am trying open port on PROXMOX ex. I want open port for vm which have the webstie. I would like to reach this out of the proxmox. Should I open ports on Proxmox or in VM?

I tink you would need to add a custom iptables rule to port-forward.

Sure. Gonna penetrate the documentation. Okay... so last question is: I am testing NAT on proxmox. And i see that my VM`s dont have internet connection. Should I add somethink else?

Did you set up your PVE hosts IP as the gateway for the guest OS?

 

[kekosz]

This is conf of VM network interface
where 10.10.10.0/24 is a private IP
where 192.168.1.0/24 is a "public"

And there is conf of PROXMOX network interfaces

And this is routes print of VM

 

[Dunuin]

Gateway then should be 10.10.10.1 and not 192.168.1.8.

Yes I edited that, to 10.10.10.1 but still not works :/

Okay, I am done.... I needed UP vmbr1. I didn`t see this until i typed ip -c a. Thank a lot for help. I think I can close thread

I use proxyarp so no need for nat on the wireless intface, works beautifully !

Can you share your configuration?

There is no configuration, just turn it on on your wifi interface !
