This article explains network settings for Additional IPs from Hetzner .
The following fields in the Create IP Pool form have to be filled as below:
- Gateway : Use Gateway same as provided by Hetzner.
- Netmask : Use netmask of the IP same as provided by Hetzner.
- Routed : Please check on 'Use routed network' option.
- Adding ip : Add ips along with Mac generated from Hetzner panel.
Note : OpenVZ does not require mac for the ips.
Using Multiple IPs in a vps will not be possible since Hetzner does not provides option to generate same MAC for multiple IPs.
Having same MAC generated would be required since Virtualizor will add the IPs as alias on eth0 within vps.
