GhislainG :
Your server has 2 NICs. One connected to the Internet modem or router and another one connected to a LAN switch. All PCs will also be connected to the LAN switch. Since you have a server, it also acts as a router if it has more than one NIC. As long as your DNS has a forwarder to an Internet DNS, it will know that the PC is trying to access a non-local IP address and it will route traffic accordingly. In other words, the server will behave just like an Internet router that you may have at home.
will thIS be hard to SET UP?
CAN I FIND A STEP BY STEP INSTRUCTION ON HOW TO SET THIS INTERNET CONNECTION WITH 2 NIC IN A SERVER
