I’ve been using OpenVPN to access a distant network at a friend's place for about a decade. It was a total PITA to get working years ago & has also been a PITA whenever the DDNS used for it needed to be changed. The small network at my friend's place is ~120 miles away & I could not visit his place during the ongoing emergency conditions & he is not technically oriented enough to help me fix my remote access, sadly. This all became more important when I replaced my main PC at home with a box running Ubuntu 18.04. I tried everything I could find to get it to connect via OpenVPN, but it only failed. Trying to get help at the OpenVPN 'support forum' brought only contemptuous, denigrating replies as well as demands to pay nameless, faceless strangers just to tell me what I have to do rather than any helpful support. (A truly nasty forum that I will not bother with again.) My temporary solution was just to keep my old windoze box around for that connection and/or just use Anydesk when no file transfers were needed. Also in the meantime... During all the years since originally setting this up I have made a point to stay alert for better remote access options - and avoided all the nasty membership/app centered things (like Teamviewer, for example). The only exception was Anydesk in its free version, but sadly both OpenVPN & Anydesk connections have become incredibly slow via the heavily loaded internet in his small town lately. For me - the one good result of this crazy time has been the accelerated emergence and/or development of better remote access options and it has been a pleasure to see these things emerging & maturing. Wireguard came up for me 1st & looking into it revealed that it was not really a better option by itself; Next Tailscale came along - which looks to simplify Wireguard immensely...BUT=> Then came ZeroTier. Wow. To say that I am very favourably impressed by it is a huge understatement. So simple - so easily installed & set up - and FAST !!! In Ubuntu it installs & joins up with a mere 2 commands followed by making a single checkmark at the network page, then...BAM !! Open a remote viewer app to the newly added IP, and there is that desktop. It creates a whole new & additional virtual network for remote access and has shown me that OpenVPN needs to become extinct now because ZeroTier has (thus far…) been so vastly much better. Final result: I now have no further need to waste my time & efforts trying to ‘please’ the demands of OpenVPN, so=> For me, this means problem solved. Also: My friend now has both his home PC and his notebook PC on that same new virtual network and I have already used it to help him at his home from ~120 miles away. Multiple locations are another huge benefit of this new tool as I have some other friends who are MUCH farther away and was able to install this & join them into my virtual network in just minutes time. Is this perfect enough for the purists ?? Most likely not, BUT; It serves well to provide for our needs at least during this crazy time.
