There is no Gateway on vmbr0.

Why do you have an ip address on enp1s0 ?
On my proxmox server that interface is empty. I have ip address and gateway configured on vmbr0.

 

[azrod]

Yes, the configuration example on proxmox wiki said set no gateway :

In Routed configuration section : https://pve.proxmox.com/wiki/Network_Configuration


I have add gateway on vmbr0 but this not solved my problem

I have ip address on enp1s0 because i want to access on my proxmox with an ip address from my local network.

Okay, sorry. Now I see what you are trying to do here.
Your ip addresses are not public addresses but for internal networks.

Yes they are internal networks IP.
The network 192.168.1.0/24 is my local network and the 172.16.1.0/24 is my network in promox

Correct me if I'm wrong, but routed config is for running pve at a hosting provider.
If you are running pve at home on a local network than routed config is not for you.
Why do you need routed config?

 

[azrod]

I'm not need routed config, i just try this configuration because the default bridge configuration not worked for me.
I'll try the default configuration again and get back to you.
But with the default configuration, in section vmbr0, it's possible to set 172.16.1.0/24 network or it's just worked with my local network (192.168.1.0/24) ?

So, with the default conf I managed to make this works.
But I can't add a second subnet who go to internet. You have a idea ?
Thanks

 

[Spoonman2002]

Are you trying to create seperate networks?
Maybe you can try VLANs.

You can create several vmbr Bridges, they are a sort of networkswitches, each with their own subnet.
But only one can have a Gateway (internet).
So maybe you have to add routes in your router/firewall.

 

[azrod]

Yes I trying to create seperate networks. I will try VLANs.

Thanks for your reply

There is no Gateway on vmbr0.

maaaaan, I lost whole evening to realize that when I set Static IP and forgot to fill this field (for future wanderers: in proxmox gui, in network tab for LXC, when you set IP4 and IP6, cant miss it;] )
thx to you, for me it solved my problem
