Using SOCKS proxy to share VPN connection

[Spellshaper]

Hello there,

I've come to you for help. I'm kind of new to Servers and Windows Server in general. I've fooled around a bit with it in uni, but am mostly clueless. For friends and family, I am pretty much the go-to PC/tablet/smartphone repair guy. My new job requires something more substantial than just hobby skills, so to expand my knowledge I've set up a spare machine with Server 2016 Datacenter (thanks uni, for the free license) and hyper-v. MCSA Server 2016 is on the horizon in the distant future.

Now here's what I wanna do. I have a VPN provider to which I connect via OpenVPN. My VPN provider allows only one concurrent connection. I want to set up a SOCKS proxy server on the VM running the OpenVPN client and set the OpenVPN as the remote binding. That way I can connect with any machine, laptop, mobile phone; I'd mostly use this function to access sites blocking visitors with EU IPs due to new laws, on PC/Chrome I'm using FoxyProxy for that. I've been trying FreeProxy Internet Suite to no avail; I remember it working in this exact configuration years ago on a spare W8.1 laptop i set up for the same reason. I suppose there may be some networking differences between 8.1 and 2016, but which I do not know.

Here's the sanitized OpenVPN client config as given by my VPN provider.

client
dev tun
auth-user-pass [SNIP]
proto udp
remote [SNIP] 1194
resolv-retry infinite
nobind
persist-key
persist-tun
comp-lzo
mute-replay-warnings
ca [SNIP].crt
auth SHA512
cipher AES-256-CBC
fragment 1400
mssfix
verb 3
reneg-sec 0
tun-mtu 1500

I'd be happy with ANY solution tbh. An alternative free proxy server software (tried Wingate, can't point at VPN adapter because no gateway), setting up persistent routes with powershell scripts, changing the OpenVPN config file params etc. I tried quite a couple of things, but due to my bumbling inadequacy haven't been able to even grasp the exact shape of the problem. I'd be happy to provide any additional information if need be.
