Hello everyone!
I have a dedicated server in OVH with Proxmox VE 7.2-11 installed through the OVH's ready-to-use template.
The public IPs from the dedicated server are setup as below:
IP: 15.xxx.xxx.xxx/24
Gateway: 15.xxx.xxx.254
Additionally, I bought some Failover IPs, as it follows:
FO IPs: 51.xxx.xxx.56/30
In Proxmox network, I have two network devices:
1) enp5s0f0
2) enp5s0f1
And there is two Linux Bridges:
1) vmbr0 (setup with the dedicated server IPs 15.xxx.xxx.xxx/24 and gateway 15.xxx.xxx.254)
2) vmbr1 (setup with none ports/slaves and FO IPs 51.xxx.xxx.56/30)
I've created a VM and inserted the Virtual MAC from the second FO IP (51.xxx.xxx.57) and set it up to use vmbr1. But with this setup, the VM doesn't connect. If I switch the bridge to vmbr0 it works just fine.
I also tried to add this last line to the file /etc/network/interfaces, as I saw in https://forum.proxmox.com/threads/proxmox-ve-6-ovh-ip-failover.94340/ but it didn't work for me:
auto vmbr1
iface vmbr1 inet static
address 51.xxx.xxx.56/30
bridge-ports none
bridge-stp off
bridge-fd 0
post-up echo 1 > /proc/sys/net/ipv4/conf/vmbr1/proxy_arp
Tried to insert both 'post-up echo 1 > /proc/sys/net/ipv4/ip_forward' and 'post-up echo 1 > /proc/sys/net/ipv4/conf/vmbr1/proxy_arp' too, but couldn't get it to work.
My intention is to use all FO IPs in this single VM, as I will build it as a Mail Server. And leave the dedicated server IP only for Proxmox management panel.
Please, could you help me to find out how can I set this up?
How can I insert my FO IPs in Proxmox so that I can use them into my VM?
Many thanks!
