Looking for all-in-one device that has a /16 subnet DHCP server, OpenVPN client and firewall

Hey guys, I'm looking for a router that has

• OpenVPN client
• DHCP server for /16 subnets
• firewall

so basically like that router people have at home, just for the professional sector.

We have multiple DCs that I want to connect to a central OpenVPN hub, that hands out IP adresses to clients. I don't necessarily need a web application firewall, since there are not workstations in our DCs. There are between a few hundred and 2000 clients in every DC.

Up until now we did it with one or more vmhosts and all services as VMs. But at this point it became to much work to set up this for every DC. I just want a box that I can configure, plug in and be done.

I was on the Juniper and Fortinet websites but was kinda overwhelmed by the options. I just need a push in the right direction on what to look for.
