ipv4 static

[MKnerd]

Hello Everybody,

i have a dedicated server with proxmox, i made a several VPS but with linux i am not able to set a static IPV4.
i try to change, in this VPS, the file /etc/network/interface with
auto eth0
iface eth0 inet static
address [IPv4 address of your server]
netmask [Mask of your IPv4]
gateway [Gateway of your IPv4]

but the VPS couldn't connect to internet.

i hope someone could help me to fix this issue.

thanks in advance

Hi
My system is running by
1ip to host proxmox
And
6ip’s ( one subnet ) configured for my VM

And all those ip’s configured as a route system not bridge.

my system is a dedicated server with 1 ip for this machine and 6 ip failover
i create 3windows vm and i want try to create a linux server (without using container) but i not able to connect this one

i try to cahnge /etc/network/istances
with this

auto eth0 (ens18)
iface eth0 (ens18) inet static
address [IPv4 address of your server] (1.2.3.4)
netmask [Mask of your IPv4] (255.0.0.0)
gateway [Gateway of your IPv4] (5.6.7.254)

but nothing don't work.

 

[Shamim4s]

OK let me more clear ..!!
do you want to use failover ip to you VM ? or you have any additional IP's ?
or you do not want to assice any dedicated IP to VM only internet connection ?

 

[MKnerd]

I want to use my failover ip.

 

[Shamim4s]

ok, i'm not so much expert. but i have faced my problem and kill lots of my time. thats way i replied to you. other then this group also dosnt support me. hetzner also.. F***

Even your additional subnet IP's will less your cost like 6 additional ip's will 14euro and 6 failover ip will cost maybe 24euro..

any way here is my configuration

check if you can understand

auto lo
iface lo inet loopback
iface lo inet6 loopback

auto enp2s0
iface enp2s0 inet static
address 136.000.000.213
netmask 255.000.000.192
gateway 136.000.000.211
# route 136.000.000.192/26 via 136.000.000.000
up route add -net 136.000.000.192 netmask 255.000.000.192 gw 136.000.000.193 dev enp2s0
post-up sysctl -w net.ipv4.ip_forward=1


# device: vmbr0
auto vmbr0
iface vmbr0 inet static
address 136.000.000.121
netmask 255.000.000.000
broadcast 136.000.000.178
bridge_ports none

Ps another note about OVH and Proxmox.
Proxmox over zfs use 0.7 version. In case of failure, OVH give you the ability to restart on a rewcue that has a 0.6 of zfs. The issue is if you enabled of zfs feature of 0.7 you can just mount the filesystem in read only due to the 0.6 zfs reading it. So be carefull if you play with network settings and you ran zpool upgrade
