We normally setup all of our severs behind firewall with private IP addresses and then do NAT to public ip addresses.
For example I just spin up a new Ubuntu 20.04.2 LTS server and setup 3 private static IP addresses for example 192.168.10.2, 192.168.10.3, 192.168.10.4 on this server and run the install script. All is fine to this step.
All of this IP addresses have translation on proper ports to public IP addresses for example 220.127.116.11, 18.104.22.168, 22.214.171.124
On server configuration I wanted to select 192.168.10.2 for management but this does not work. I can only select 126.96.36.199, 192.168.10.3, 188.8.131.52
Note 184.108.40.206 is our firewall public ip address.
I guess this is quite unusual setup. Is this supported or?
Our plan was to do
192.168.10.2 (management) NAT 220.127.116.11
192.168.10.3 (website 1) NAT 18.104.22.168
192.168.10.4 (website 2) NAT 22.214.171.124
Thank you for your help!
