On what hardware to raise the Internet through the tunnel (Provided that the gateway needs gigabit)?

Question

Mikrotik

Given.
Point A. Gigabit link to the world and to UA-IX.
Point B. In the world megabit-two, on ua-ix - 100 megabit.
It is required to put Point B on the Internet (ideally, everything except UA-IX) through point A. So that capricious clients of point A have gigabit (I perfectly understand that gigabit-100 megabits = 900 megabits). If there is at least 20-30 megabits at point B, this is already a success.
It is important to prevent a significant deterioration at point A, provided that Asus RT-AC66U is now at point A, which, according to the speedtest, gives 800-850 megabits.
There are two options:
1. A Ubiquiti EdgeRouter ERPoe-5. (There is an inexpensive used one. ERLite-3 is not suitable, you need at least 3-4 ports on the LAN, ideally with POE.)
B Edgerouter - X/Ubiquiti EdgeRouter Lite (ERLite-3 also used)
2. And Mikrotik HAP AC2
B - ?
The second option is fundamentally cheaper, but will it work? And isn't the first option too redundant?
PS And yes, at point A, an OpenVPN client must still live to bypass blocking.

Answer 1

Excellent fluff. If we let the second client access the Internet through vpn ... then how will he get from 2 megabits to 20? Suppose we let all 100 megabits through gigabit through the Ukrainian local network. That as in the first case there will be gigabit instead of 900? Mikrotik hEX RB750Gr3 presses 400 megabit ipsec

Answer 2

Take 2 Mikrotiks and don't fool yourself. What's the budget? if it allows, then feel free to take them

Answer 3

A piece of iron capable of gigabit vpn costs so much that it will be cheaper for you to dig a cable to UA-IX yourself;)
