GRE over IPSec does a great job, overhead is less than EoIP, although the difference is almost not noticeable.

1) Less CPU load
2) Less brands with routes
30 Speed ​​will not cut

Answer 3

I would use pptp if you don't really need encryption. OPVN if you need to hide traffic

Answer 4

As they say, there are no comrades for the taste and color. For many years I tried, probably, all possible options, in the end somehow it turned out by itself that l2tp is everywhere.
If you need to encrypt the tunnel - a great guide to setting up L2TP + IPsec on the site of Kirill Vasiliev.
If you need L2 between offices, it is preferable to set up VPLS over a tunnel .

Answer 5

OpenVPN or L2TP + IPsec. Although, taking into account the peculiarities of the implementation of OpenVPN on Mikrotiks (no compression, no UDP mode), I would still do it on L2TP + IPsec.

Answer 6

Which tunnel to use for two offices?

If there are only two offices and no third-party connections are expected, that is, you need to stupidly connect two departments with a closed tunnel, then the simplest is an openvpn tunnel with symmetric cryptography. When a single key is used for symmetric encryption.
It is done quickly by means of openvpn itself. No need to generate any intermediate keys and certificates. Works quickly and in both directions.

Answer 7

If you use the same provider and are in the same vlan, then EoIP + IPSec.
