Network setup for Hetzner

[tahayildiz]

Hello,
i hop you guys can i help me.
Currently i have proxmox in the hetzner cloud on a root server. I have 3 Public IP-Adresses.
1. Public IP: 138.XXX.XXX.126 (Proxmox Interface)
2. Public IP: 138.XXX.XXX.96 (pfSense WAN -> LAN)
3. Public IP: 138.XXX.XXX.105 (pfSense WAN -> Mailserver)

Hetzner Public IP Information:
Gateway: 138.XXX.XXX.65
Netmask: 255.255.255.192
Broadcast: 138.XXX.XXX.127


This is the current /etc/network/interfaces config on my proxmox:

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

iface enp0s31f6 inet manual

auto vmbr0
iface vmbr0 inet static
        address 138.XXX.XXX.126/32
        gateway 138.XXX.XXX.65
        bridge-ports enp0s31f6
        bridge-stp off
        bridge-fd 0
        bridge_maxwait 0
        up route add-net 138.XXX.XXX.96 netmask 255.255.255.255 gw 138.XXX.XXX.65 dev vmbr0
#       up route add-net 138.XXX.XXX.105 netmask 255.255.255.255 gw 138.XXX.XXX.65 dev vmbr0 #if this is uncomment the private networks doesnt reach out to the internet. If its commented i can reach from the private network to the internet over the ip: 138.XXX.XXX.96

auto vmbr1
iface vmbr1 inet manual
        bridge-ports none
        bridge-stp off
        bridge-fd 0
#pfSense LAN

auto vmbr2
iface vmbr2 inet manual
        bridge-ports none
        bridge-stp off
        bridge-fd 0
#pfSense DMZ

auto vmbr3
iface vmbr3 inet manual
        bridge-ports none
        bridge-stp off
        bridge-fd 0
#pfSense Mailcow

And yes i put the mac adress of the host to the vmrb0 of my firewall.

I think that something doesnt work if vmbr0.
I hope someone can help and get this working.
Thank you

Have you enabled IP forwarding?

See "Enable IP Forwarding on the Host" in this documentation

Also, remember that the VM should have the IP address of the proxmox interface as the gateway.

Alternatively, use bridged networking, it's easier to set up.

I didnt added the mac address to the vmbr0, its something with hetzner
