I have followed these steps:
1. I have set all the servers eth0 cards with a public IP.
2. I have connected all the servers to the switch in unmanaged mode.
3. I have connected the public network cable in the switch too.
All the computers would be on the web but know a question comes:
Do the Servers communicate between themselves and resolving the IP internally ?
184.108.40.206 WEB Server
220.127.116.11 DB Server
18.104.22.168 MAIL Server
If the WEB server wants to know some information from the db server must resolve the path to reach the db server in the right way?
