Hetzner root server network configuration cant figure it out? Quick fix?

[chgo2oc]

Hey Community,



I was wondering if I could get some help setting up the correct networking config for my proxmox root server.. I am new new noobe, so it kinda like jumping in to a group of people speaking German (my German teacher would be so disappointed, she was so hot though) and you only know a few words. I cannot find an easy road map to follow. I just want to run 3 or 4 ubuntu vm's, and a PFsense firewall (since that is what i use at home)



Here is the mess I have created so far.



Hardware is AMD Ryzen 7 1700X

2X SSD SATA 512 GBX

4X RAM 16384 MB DD4



During installimage Debian buster with proxmox

-Datacenter
    -Nodes
        -prox
    -Virtual Machine
          100 (Ubuntu1) (no network connection) I think I have to set this up with static
     -Storage  (shouldn’t this be nested under my Node its not)

created a vswitch vlan 4003 and linked to my server

• I dont understand if I can arbitrarily just set up a NIC, I kinda understand the naming convention en=ethernet pcibus=6 slot=0.
• How do I set up additional NICs?
• Should I purchase 4 additional IP's? or can I route to a private ip space?
  • I only see the ability to purchase 1 additional IP or CIDR /29
  • since there no DHCP CIDR/29 does that mean I could use all 8 ips? which I really dont need but I dont see away to just purchase 4 of the them.

You should not need VLANs at this point. Have you already tried one of our suggested ways of configuration?

By the way, when creating a post you can click on the button with the three dots in the edit bar and select "Code" to insert code snippets properly formatted.

thanks sorry Dominic can you take a look at this

Original Config

  GNU nano 3.2                                    /etc/network/interfaces

New Configuration

1. two things I pulled this from a very smart guy who is also named Dominic link here he has eth0 in his example is that because he might have been using ubuntu. I should keep it enp6s0 right
2. Do I need to add the line from the original network config (line below) to underneath pointopoint

up route add -net 1xx.xxx.xxx.0 netmask 255.255.255.192 gw 1xx.xxx.xxx.1 dev enp6s0

auto eth0
iface eth0 inet static
        address  138.201.203.16
        netmask  255.255.255.255
        gateway  138.201.203.1
    pointopoint 138.201.203.1
        
auto vmbr0
iface vmbr0 inet static
    address  138.201.203.16
    netmask  255.255.255.255
    bridge_ports none
    bridge_stp off
    bridge_fd 0
    bridge_maxwait 0
        up ip route add 138.201.203.49/32 dev vmbr0
        up ip route add 138.201.203.52/32 dev vmbr0
        up ip route add 138.201.203.56/32 dev vmbr0
        up ip route add 138.201.203.57/32 dev vmbr0

Thanks for you help

Dominic, I attempted the suggested configuration from the link you sent me, and didnt work. I just read through some post about the subscriptions services and why its important to support proxmox in this way. I fully agree!! Although I cant afford the $270 license fee, I think I saw a $80 community annual support..... something something.. I have no problem supporting you in that way, however if I can even get this thing to work that 80 poorly spent for me. Do you think if I ponied up (american term for put your money on the table) the $80 I could get some support on the network configuration??

Community support for the Community Subscription is done in this forum. There is no guaranteed response time. However, you will have a note "Proxmox Subscriber" below your avatar/user name in the forum to make your support visible

Could you provide the output of ip link show? Do you reach the internet on your host ping 8.8.8.8? If not, please create a backup of your current configuration first. If I insert your addresses & names into my own working configuration it looks like this:

auto lo
iface lo inet loopback

auto enp6s0
iface enp6s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address  138.201.203.16
    netmask  255.255.255.255
    gateway  138.201.203.1
    bridge-ports enp6s0
    bridge-stp off
    bridge-fd 0

Note that my enp6s0 is set to manual and vmbr0 has enp6s0 in bridge-ports. vmbr0 then holds the ip address of your host. Please try this (don't forget to reboot) and check if you reach the internet using ping.
