Dual physical NIC setup

[Sgt_Wirehead]

Hello Proxmox gurus,

Some years ago i was trying Proxmox with a Subscription but gave up due to not being able to configure the networking, now i am looking at Proxmox again and would like to configure dual physical NICs one for the management interface on the physical network and the other for the virtual machines to access the physical network. How would one configure this type of setup? If any one has an example config file for /etc/network that would be quite helpful.

You can do this on the GUI.
Node->System->Network
Just double click the second nic in the GUI and set up your config.
Then reboot your node

Hello Wolfgang,

Thank you for the reply...
Is this what you mean?

auto lo
iface lo inet loopback

allow-hotplug enp5s0f0

auto enp5s0f0
iface enp5s0f0 inet static
    address  192.168.1.180
        netmask  255.255.255.0
        gateway  192.168.1.1

allow-hotplug enp5s0f1

auto enp5s0f1
iface enp5s0f1 inet static
address  192.168.1.181
     netmask  255.255.255.0
     gateway  192.168.1.1

Now you have 2 plain nics you have to add on one nic a linux bridge.

auto lo
iface lo inet loopback

allow-hotplug enp5s0f0

auto enp5s0f0
iface enp5s0f0 inet static
     address  192.168.1.180
     netmask  255.255.255.0
     gateway  192.168.1.1

allow-hotplug enp5s0f1

auto enp5s0f1
iface enp5s0f1 inet manual

auto vmbr0
iface vmbr0 inet static
     address  192.168.1.181
     netmask  255.255.255.0
     bridge_ports enp5s0f1
     bridge_stp off
     bridge_fd 0
     mtu 1500

this config seems to break my xrdp service for some reason

and what do i add for a virtual network that is between the virtual machines only? i will be running a VM as a dhcp server for this

You have to create a dummy bridge without physical nic.
Just add a Linux bridge on the GUI without settings.

thank you Wolfgang,

Now those are configured i have had to reenable ssh and xrdp. Not shure how or why they get disabled when doing this network setup. All good and working again.

Once I have this I can test the server tomorrow as its late here now.

Thank you for all the help Wolfgang.

 

[Sgt_Wirehead]

tested and nics are all working well

How do i install pvesm as all i get is 'command not found'?

 

[Stoiko Ivanov]

you need to run the command as root (it is in /usr/sbin and also requires privileges) ....

 

[Sgt_Wirehead]

thanks i was logged in as root but using 'sudo pvesm nfsscan 192.168.1.200' as root did it.

lol... had a brain fart thats all
