We, as the pioneering researchers(!), have a small network in our lab and the university has provided Internet access that let us access to privileged scientific resources like IEEE, ScienceDirect, etc.
I am looking for a way to connect to lab network through Internet when we are away and have this privileged access (and also be able to remotely connect to the lab computers and simulate some things).
Sadly, our network is behind the NAT-server of university, so there is no chance in a pure VPN-Server solution. There is no chance to configure the main NAT-server of university neither.
I have tried Hamachi VPN software, but as I realized Hamachi does not establish a VPN Server behind a NAT. It is actually a peer-to-peer solution for computers behind NATs over the Internet.
One Hamachi-based solution is to configure one of the lab computers as a VPN server and installing Hamachi on it. Then the distant users should install and run Hamachi on their computers and then connect to first the Virtual Hamachi Network and then the VPN-Server.
Problems of proposed solution:
But there is some problems about this:
- Will Hamachi really work on a VPNServer? Not surprisingly, Some users use linux :) Is there any linux-based Hamachi software for them?
- The procedure of connecting to the lab internal network is a little bit complex, and as you know researchers are really not good at computers. Is there any way to KISS (S imple and S traightforward)
- The Hamachi software causes some mistakes in my routing table. Specifically, sometimes I lose internet access when I connect to our Hamachi Virtual Network and I have to reconnect. Is this a common problem with Hamachi? If yes, too bad because this would confuse and annoy other less-experienced users.
Do you know any better free solution to connect to the workplace LAN that is behind a NAT?
Some words about legality:
Just as SvenW said, actions like this is a may raise some legal concerns. I asked about this and sysadmins said it is okay as far as we don't spread this access to the other people. Our team is consisted of 14 people and each of us can have his username/password to connect to. Therefore, all the activities can be logged and any misuse can be traced.
