Struggling with networking on Hetzner box.

[Jackster]

Got a new Proxmox box setup and have not worked with Proxmox in a dedicated server environment before.

Having a real struggle with the network settings and this bridging stuff.

Server details obfuscated but here they are.
Host IP 0.0.0.113
Gateway: 0.0.0.65
Netmask: 255.255.255.192
Broadcast: 0.0.0.0.127

Additional IPs
0.0.0.85
0.0.0.86
0.0.0.87
0.0.0.88



I have read and tried the two options given in this documentation but I could not get it to work inside a Windows VM.
https://community.hetzner.com/tutorials/install-and-configure-proxmox_ve

Here is my current /etc/network/interfaces based off this user's setup
https://forum.proxmox.com/threads/n...n-hetzner-dedicated-server.62440/#post-286242

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp35s0
iface enp35s0 inet static
        address 0.0.0.113/32
        gateway 0.0.0.65
        pointopoint 0.0.0.65
        up route add -net 0.0.0.65 netmask 255.255.255.192 gw 0.0.0.65 dev enp35s0

auto vmbr0
iface vmbr0 inet static
        address 0.0.0.113/32
        bridge-ports none
        bridge-stp off
        bridge-fd 0
        up ip route add 0.0.0.85/32 dev vmbr0
        up ip route add 0.0.0.86/32 dev vmbr0
        up ip route add 0.0.0.87/32 dev vmbr0
        up ip route add 0.0.0.88/32 dev vmbr0

Here is my VM's settings


I have searched around a few other threads on here as well as a few other websites with guilds on but nothing is working.
What am I doing wrong?

Thanks
Jack

address 0.0.0.85/32 on vmbr0 is not correct, you should reuse 0.0.0.113/32

auto enp35s0
iface enp35s0 inet static
        address 0.0.0.113/32
        gateway 0.0.0.65
        pointopoint 0.0.0.65
        up route add -net 0.0.0.65 netmask 255.255.255.192 gw 0.0.0.65 dev enp35s0

auto vmbr0
iface vmbr0 inet static
        address 0.0.0.113/32
        bridge-ports none
        bridge-stp off
        bridge-fd 0
        up ip route add 0.0.0.85/32 dev vmbr0
        up ip route add 0.0.0.86/32 dev vmbr0
        up ip route add 0.0.0.87/32 dev vmbr0
        up ip route add 0.0.0.88/32 dev vmbr0

Typo in the OP, my mistake.

as you use a routed setup, can you verifiy than you don't have mac address associated with ips address in hertzner panel ?

(a proxmox user have reported that it's blocking routed setup)

I have tried both with and without to make sure.

is forwarding enabled ?


echo 1 > /proc/sys/net/ipv4/ip_forward

echo 1 > /proc/sys/net/ipv4/ip_forward

yes

That echo does not report anything back though

edit, cat /proc/sys/net/ipv4/ip_forward shows yes

Got it working after a reinstall.

So I have a pfSense box running with a private local network for some VMs that don't need public-facing IPs.
The VMs can access the internet but when running an update, they are unable to connect to the repository.

Any ideas?

[edit]
Got it working with IPFire.
