Is it possible to somehow set up Express VPN on Mikroitk? I would like to set up, for example, when I connect to a 5GHz wifi, connect to VPN, and if I connect to a 2GHz wifi, don’t use a VPN. Is something like this possible?
Simply: Yes.
Yes. You can also have 2 speparate SSIDs (“WiFis”) on 2GHz (and/or 5Ghz) with only one of them tunneling your traffic through VPN.
Ok, how can I do it? Maybe some example 
Hi there... can you please post how?
