cPanel with multiple NIC's

[Clouseau]

Hello,

I have read that cPanel doesn't support multiple NIC and puts additional IP's as ip alias of primary interface (usually eth0).

I have a server with two interfaces inside my VM, I have configured policy routing and I have working network on both interfaces. Due to a how network has been designed inside Datacentar where dedicated server is, I cannot bind second IP to primary interface (eth0:0 or eth0:cp1), I can only add interface with seperate MAC and give it an IP.

So my question is: can I have problems in the future, when cPanel uprades for example? For now it works:

Under "Show or Delete Current IP Addresses" section in WHM I can see:
eth0 interface as IP1 Main/shared IP for: username1, nobody, and root
eth1 interface as IP2 Dedicated to: username2

All users will use IP1, few will use IP2. Possibility is that I will add eth2 interface in future for third IP.

Hello,


There's no restriction on NIC's but we do prefer they are added through ipaliases - essentially as long as the network works it should be fine. The documentation here explains how this works: Add a New IP Address - Version 84 Documentation - cPanel Documentation

Hi,

ok tnx. I know how cPanel adds additional IP's but I found info that is not recommended or supported. Due to specific nature of DC network, I cannot acomplish that with cPanel but cPanel sees additional eth1 interface without problem (don't need to add IP or rebuild the pool...). Cool.
