I've configured an additional network interface with only private address but i can't reach that server using this newly created address.
Here are the steps I've done:
- created 2 machines: A and B (same zone).
- created an additional ENI with a new private address
- configured a single security group with all traffic (inbound and outbound) allowed.
- attached the new ENI to A.
- configured the ubuntu box to setup the new interface (eth1 auto)
From B to A using the primary private IP I can access all services, but using the new private IP address (from the new ENI), I can't.
May I missed something?
