Hello gents! Need some input here-and i thank you in advance for your time and expertise. Need to set up a connection to a small office with 4 computers, each one has a different purpose and runs a different software, so i need to acces one of them, but not same one each time, not both on the same time. I have DynDNS Pro account with enough hosts, and i have a Ubuntu 14.04 server running inside that office as a file and Owncloud server.For now the server is connected to the internet just to update, no ports open for anything else. Option 1 : Install VPN server by Webmin, create a user+certificate and "expose" the LAN to the user from the internet Option 2: just set port forwarding to the IP-port-service needed and not bother Option 3 : install Open VPN and for each user create password+cert+ and install Open VPN client/create a VPN subnet with the features needed Well, i am open to suggestions, just it's been a while since i configured something like this, but i did it some while back, so i think i can follow some guides
A little bit of a late answer but I'd go with either Option 1 or 3. You can also do OpenVPN and "expose" the LAN to the user: https://openvpn.net/index.php/open-source/documentation/miscellaneous/76-ethernet-bridging.html
