I am already using this kind of VPN for my needs. I am using L2TP for A mikrotik to mikrotik connection, for Mikrotik to IPHONE(with ipsec), android connection (road warrior).
Hi,
I have a lot of experience using mikrotik and openVPN.
I used openvpn in different config like linux server - mikrotik client , mikrotik server - mikrotik client, with certificates , without certificate .
