PROXMOX on Azure Help

[Teo_80]

Hello,



I have installed proxmox on premises and able to provision VM and provide networking with NAT.

KVM 10.03.4 (public) <--> NAT (192.168.0.0/24) <--> VM (192.168.0.100)

Like this and with port forwaring i am able to access vm.

What i need is one static ip per vm so my question is how i can apply different static ip to each vm?
Any thoughts?

Regards

Teo

Have you looked at the relevant section in the manual? https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_choosing_a_network_configuration

If you can have multiple MAC addresses on the interface you can do the simplest setup with the bridged interface (vmbr0). For other possible setups check the manual I linked to

Thanks for prompt reply. I have looked at it previously.

As epxlained my current setup is using NAT, since Azure allows only 2 physical Nics per instance

NIC 1 ---> 10.0.3.0/24 --> ETH 1 --> VMBR0 (NAT) --> VM (192.168.0.1 PRIVATE)
NIC 2 ---> 10.0.4.0/24 --> ETH 2 --> VMBR1 (NAT) --> (192.168.1.1 PRIVATE)

Like above everything works fine and all VM are getting public IP ( 10.0.3.0 - 10.0.4.0), which does not work since need one dedicated ip per VM for hosting purposes.

Thanks

I am a bit unsure why you think that the vmbr interfaces do NAT. Could you please show the content of your "/etc/network/interfaces" file? Redact the configured IP addresses or change them to something different.

Without additional settings the vmbr interfaces are like switches and not routers.

With the setup as you described it your VMs should actually be connected to the public network and if you give them a public IP it should work.

To have a real private network on your Proxmox server you would need to add a new bridge interface that has no "Bridge Port" configured.

Thank you for your reply.

I have just vm internal network configured at vmbr0 and not birdged with eth0
Azure as far as i see dont accpet bridge mode, if i try to bridge with eth0 host vm loses connectivity.

Keep in mind this is neseted virtualiztion setup.

Any suggestions?

Thanks

Check the reference documentation (as posted by @aaron ) - I think you want a NATed setup - https://pve.proxmox.com/pve-docs/ch..._nat_with_span_class_monospaced_iptables_span

Thanks for your input. NAT works fine for one ipc. If i add secondary one not just does not work.

I can ping outside from host VM (proxmox) but not from nested vm. IPs are even in separate subnet and does not work. I really drives me crazy!!

 

[Stoiko Ivanov]

please post your:
* `/etc/network/interfaces`
* ouput of: `ip a` , `ip r`
* `iptables-save`

also try pinging the host from a guest, and the hosts default gateway from a guest and post the output
