Hi
I am planning to connect to sites over WAN, I need to transfer between them some packets within the L2. Both sites must be kept within the same LAN IP range.
I believe I got 2 options here Eoip or OpenVPN (bridge). I am planning to use 2 of Mikrotik routers.
I need to set up both server and client OpenVpn if using OpenVpn.

I have some questions:
Which is the lowes model router (cheapest) which supports either OpenVPN or /and Eoip ?
Which level of RouterOS should I use?
Is it possible to set up OpenVPN or /and Eoip in a different range of IP addresses apart from my Local network - what I mean - I need only 1 device on each site to see each other over the internet.
They do not need to have access to the Internet.

Is it possible to separate this OpenVPN or /and Eoip network from my LANs on both sites - i mean this tunnel is only used by this 2 devices all other devices, which are using the Internet must use default Gateway from my router - not via the tunnel to avoid overwhelming this tunnel.
Thanks.

Whatever mikrotik device can do that. The difference is in performance. The requested routing rules are freely configurable according to your needs.

if you wanna do everything in mikrotik for medium scale this router (RB2011UiAS-RM) is good
and you can establish the internet connection in router to access remote through the internet and when you established vpn or eoip can reach the router through eoip or vpn
and you can use different ip in both side of network just add a static route for reachability to side

In this case rather buy 750Gr3 instead. It is cheaper and more powerful. But there is no clue how to size the router from the performance point of view...
