You can use either of those switches to route between vlans but the main problem is neither of those switches support NAT and you usually need this because you will be using private IPs on your network.

Unless the ISP does NAT for you and they usually don't you will need either a firewall or a router between the ISP router and your switch so you can do NAT on your private IPs.
