Hetzner Routed Config issue

[mazenelzanaty]

I have a dedicated server and a subnet on Hetzner, decided to use Network Configuration Hostsystem Routed config, was following their guide, https://community.hetzner.com/tutorials/install-and-configure-proxmox_ve

Here's my server config:

auto lo
iface lo inet loopback
iface lo inet6 loopback

auto enp195s0
iface enp195s0 inet static
address x.x.xx.220
netmask 255.255.255.192
gateway xx.xx.xx.193
pointopoint xx.xx.xx.193
up route add -net xx.xx.203.192 netmask 255.255.255.192 gw xx.xx.203.193 dev enp195s0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/enp195s0/proxy_arp

auto vmbr1
iface vmbr1 inet static
address xx.xx.xx.40
netmask 255.255.255.248
bridge_ports none
bridge_stp off
bridge_fd 0

What should my vm ip config be like?

I tried having the gateway and the server's gateway and the server ip address, both didn't work

Netplan config on vm:

network:
    ethernets:
        ens18:
            addresses:
            - xx.xx.xx.41/29
            gateway4: xx.xx.xx.193
            nameservers:
                addresses:
                - 1.1.1.1
                - 8.8.8.8
    version: 2

your vm gateway should be your vmbr1 ip address.

what is your /29 subnet ? (juste be carefull that you can't use first && last ip address of the subnet)

 

[mazenelzanaty]

Isn't vmbr1 ip address is the network address? for example

I have a subnet at 95.217.x.40 / 29

So the vmbr1 address should be 95.217.x.40?

and the vm gateway should be 95.217.x.40 too?

you can't use first ip (95.217.x.40 : network address) && last ip (95.217.x.47 : broadcast address).

so, you need to use 95.217.x.41 for vmbr1 , and for your vms (95.217.x.42-46)

i see, but what if i used bridge?

 

[mazenelzanaty]

the network address in the vm for routed config will be 95.217.x.42/29?
With the gateway 95.217.x.41?

the network address in the vm for routed config will be 95.217.x.42/29?
With the gateway 95.217.x.41?

yes

Thank you, it's working

ilk ip'i (95.217.x.40: ağ adresi) && son ip'i (95.217.x.47: yayın adresi) kullanamazsınız.

bu nedenle, vmbr1 ve vms (95.217.x.42-46) için 95.217.x.41 kullanmanız gerekir

When you do this, it should be.
