Which router to choose to combine two remote networks?

Question

Computer networks

Tell me, please, you need to combine two remote local networks with different addressing. There is a low-speed VPN for applications (from office A to office B), provided by the provider for a horse price. At office And win2012 is engaged in vpn routing. For a general application, it is enough, but does not pull the file hosting services of both offices, so it is still installed (not configured) as a WiFi bridge or an external access point Ubiquiti NanoBeam M5-400.
Please advise the cisco router model, tp-link (inexpensive, probably entry-level). Or can all this again be implemented programmatically at the windows/linux/bsd level?
Number of hosts on each side 200-250.

Answer 1

And the question price?
As though Cisco at least +20k. TP-Link does not seem to have a VPN.
If you take it, then probably Mikrotik, take 2011UAS as the base. Although it probably won’t withstand 200-250 clients, you need something more serious Mikrotik Cloud Core Router CCR1009-8G then this.
