You're great!
I'm using 7.10.2 and it doesn't work but using 7.8 it's ok!
Thank you very much!!!
I made those changes for this reason.You do not need to test both wifi interface since you always change them at the same time.
But if for some reason interface are not the same status, you change is ok.
I have already configured the L2TP server with IPsec on Mikrotik and it works perfectly but now I would like to use OpenVPN.I would suggest you use L2TP/IPsec, it will be easier for you...
Thank you so much for your answer!
