Good day, gentlemen, please help Alyosha)
I just wanted to raise vpn. very urgently and very quickly .. because there is no knowledge in this area.
Judging by the comments, I chose not the best way to raise vpn.
the server ran through the command and installed everything. as a result, I have the address http://***********:8080/
And what should I do with it? I mean where to enter all these passwords that the script offers me.
I'm on a Mac. and I don’t catch up. Che where and how .. sorry for some triviality in my message ..
I enter the data, correct. Login: Password. in the address bar I enter the vpn ip along with port 8080 ..
maybe I'm doing something wrong .. maybe I need to correct something in the additional settings?
