Topic : Config and Routing of Subnet in Virtualizor

Posted By: svenhege on May 10, 2015, 6:41 pm

Hello!

We have an installtion of virtualizor 0n a Hetzner Server with KVM. We have with this server 3 single Ip´s and a /28 Subnet. The single ips are working when setting up a vm. The internet access does not work for the subnet. We have the subnet gw configured and the new VM gets the config which is ussually correct. The internet does not work!

Any suggestions?

Regards Sven

Hi, i got a Ded from hetzner i have done what this page is said http://www.virtualizor.com/wiki/NAT.

But my ips not reachable i cant access internet from my vms.

i have used one usable add ip gateway for my vms.

Here is the my config

/etc/sysconfig/network-scripts/ifcfg-viifbr0

DEVICE=viifbr0
BOOTPROTO=none
ONBOOT=yes
HWADDR=08:60:6E:46:FB:46
IPADDR=144.76.56.xx ---> main ip addres
NETMASK=255.255.255.224
SCOPE="peer 144.76.56.xx" ---> main gateway

/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
HWADDR=08:60:6E:46:FB:xx ---> main mac addres
BRIDGE=viifbr0

now we use the first usable ip as gateway for VMs

/etc/sysconfig/network-scripts/ifcfg-viifbr0:1

DEVICE=viifbr0:1
TYPE=Bridge
BOOTPROTO=static
IPADDR=136.243.212.xx ---> main usable additional ip
NETMASK=255.255.255.224
ONBOOT=yes
DELAY=0
STP=off

/etc/sysconfig/network-scripts/route-viifbr0

ADDRESS0=0.0.0.0
NETMASK0=0.0.0.0
GATEWAY0=144.76.56.xx ---> main ip gateway

Hi,

You don't need to do anything on server , just need to add ip pool on panel .
Incase of subnet ips you need to follow our guide.
And if you have separate ips then add the ip pool with the settings provided by your data center with mac address generated on their panel.
I assume you are using KVM Virtualizor.

I fixed the issue by adding

iptables -t nat -A POSTROUTING -o viifbr0 -j MASQUERADE

issue few commands
echo 1 > /proc/sys/net/ipv4/conf/viifbr0/forwarding
service virtnetwork restart
systemctl stop systemd-networkd.socket
systemctl disable systemd-networkd
systemctl disable systemd-networkd.socket
