[janiali]

Dear all,

I am have installed Centos 7 as my Old server is running Centos 6 and I have noticed that centos is going to EOL in November 2020 . So I want to migrate to new OS 7.
Here is the details :-
I am having OVH Dedicated Server .
I am running Host with Proxmox 6.2-4 on my Dedicated Server
Then I have created a container and added 3 IP address in Proxmox eth0, eth1, eth2

I am trying to have multiple IP address to multiple cpanel accounts. but the issue is multiple IPs in centos 7 are not working as cpanel ipaliases are not working properly.

Anyone having this issue or can help please. I have gone through lots of forums from cpanel, proxmox and ovh all but nothing working .

i have tried by disabling network manager .
I have tried using bridge configuration from ovh,

Please, Please anyone help me with Centos 7 and Cpanel .

Only way i've been able to get it to work was to use the same MAC address on each IP (setup in OVH)
