From my ISP I am getting one RJ45 Port from the Modem.
One IP adress is advertised by DHCP, but beside that I have an IP range I need to use for servers.
On the primary IP adress that is advertised by DHCP I need a router that connects hosts to the internet through NAT. But some servers should be assigned a static IP address from the range I got from my ISP.
Those hosts would need to be either on separate ports where NAT is disabled or the router needs to be configured to apply NAT only on hosts that are not from that range.
For the Port based solution the router would ideally have 8 Ports.
I am quite new to this and I hope my assumptions above are correct.
So my question is:
What are the specifications I have to look for when I want to realize a network infrastructure as described above?
What kind of network equipment would I need to solve this problem?
Is there an easier way like just putting a small Hub/Switch in front of the router and connect the hosts with static IP addresses directly to it?
