Andy says
Surely there is some steps missing here? at the end of step 2
Ahmet Bas says
Andry, thanks for the information. We will update this article asap.
Ahmet Bas says
Andy, it's a bit late but we added the missing part at the end of step 2.
Thomas says
But you never did…?
Ahmet Bas says
What did we not do?
Todd says
Preshared key entry for one thing
Ahmet Bas says
Thanks, we will update our article.
Ahmet Bas says
Hi Todd,
The missing part at the end of step 2 with the preshared key is added.
nick says
Hello, what needs to be changed at the end of step 2, it says "click Change Adapter Settings" but does not list settings… i went through the whole instruction set, and i can connect with a Mac OS client, but not windows… not sure why…
Ahmet Bas says
Hey Nick,
It came to my attention that some steps were missing at the end of step 2 which is added now. You should now be able to use this article to connect.
Bryan says
Keep getting the error 'LT2P Connection attempt failed because the security layer encountered a processing error during intial negotiations with the remote computer'.
Ahmet Bas says
In Step 2, near "Open Security tab" you can configure the security layer. I would start debugging from there.

after i connected to the vpn from my windows 10 machine, i could no longer use the internet – i cannot browse or access my email. how do allow access? i will probably find an answer searching around, but showing a solution to this problem would be a nice bonus.
Ahmet Bas says
Did you configure the server-side? You have to enable network traffic you can check our article here:

wali says
On step 2 configure VPN
I think we should type the VPN Server ip address.
Let me know if I made mistakes.
Ahmet Bas says
That's correct!
Eddy says
Hi there, do we need to setup port forwarding on the router.
i tried the above steps and didnt went through
Ahmet Bas says
It depends on your configuration. Our articles are written based on our network setup.
Haven Skys says
trouble with your network setup with this article is that you appear to have created a VPN network connection on a local network. Not entirely useless but less useful (not many people are trying to hide from other people on their own network). Incredible article though.
You must be young, please consider that the purpose of this type of VPN is to give access to a remote user (not on the same network) access to your network resources. That would mean the server is behind an internet-facing router. I'm sure the firewall settings for any router is easy and your reservation is unnecessary to simply say UDP 1701, 500, and 4500 need to be directed to the 2019 VPN server. But those aren't right either. maybe with all your article writing wisdom you can get your spirit to look a tiny bit deeper and answer the question so this impressive couple of articles can be useful to more than people testing this out.

This is not true, this connection has been made to a public IPv4 address (see screenshot).
> your reservation is unnecessary to simply say UDP 1701, 500, and 4500 need to be directed to the 2019 VPN server.
This article is not about Windows Server 2019.
Are you sure you're replying to the correct article?
