I suggested wireguard, or windows server built in VPN. However he wants to pay for reliability and security. What options do I have? UK based.
Neither of us are IT professionals, and generally learn on the job. I have set up a wireguard VPN for my own homelab but my experience is somewhat limited.
What are you using for a firewall? To streamline support contracts you may want a supported product from them, or one that you know works well with your IAM solution.
Implementing a VPN is something you don’t want to learn on the job. Not because it’s difficult but because screwing up a setting will make your data and potentially entire environment vulnerable.
Windows Server VPN is an enterprise solution. For a small business it is always my second choice, the first would be the firewall appliance at your network.
Not a good idea for non IT folks to stumble through this kind of thing. I’d consult an msp to get it stood up for you, and also to advise you on what solutions will actually work for whatever your actual needs are.
Wireguard with 2 factor is a secure way to do it. Limit the firewall rules first with the Wan address and test it! You can limit the connection to 1 test server with 1 open port. If you don’t know where I am talking about. Don’t do it yourself!
I did not see this question in the thread yet. But why VPN? because of some file server? what resources do you need? maybe some cloud solution will fit your use case better?
