Which Cisco Router to Choose?

Question

DHCP

Good day everyone! Such question what tsiska to choose for the enterprise on 200 computers.
There is an enterprise in which network more than 200 computers and other network equipment. The question arose about buying a tsiska that can distribute a different range of IP addresses. There is a main building to which the Internet comes and in which there are Samba servers and a SQUID proxy server. There are also detached buildings, each with 10 to 20 PCs.
I would like to install CISCO, hang the main building (with Internet) on one port, and hang a separate building on other ports. That is, to issue different subnets for each port of the tsiska (vlan).
What equipment is suitable for this? Tell me please.

Answer 1

Based on your requirements: 200mb NAT + internal routing and VPN in the future. I would still choose 3945 so that it is enough for everything and in the future most likely you will not need to change it
