Hello Mr Andrija,
Thank you for your support, You are very right.
I have two NICs on the Host enp0s25 and enp3s0,
I plan to use
- cloubr0 for the management traffic and guest traffic
- cloubr1 for the public traffic
Iβm going to label them accordingly in the physical network settings
Before I continue, does this networking configuration look okay to you?
