Windows 10 built-in VPN - connection to FRITZ!Box, possible?

Hi.

I’ve set up VPN server in my FRITZ!Box 4040. Using Android and IPSec VPN client (native mobile system function) I’m able to connect to my LAN from outside my network.

Question is - is there a way to do the same without installing proprietary Fritz! software? Problem is, that I want to have access to my home LAN from my office, but IT policy won’t allow me install any software.

I was trying to enter new VPN connection in “native” Windows VPN, but there are too few fields, comparing to Fritz! VPN settings:

Fritz!Box VPN Windows VPN (L2TP/IPSec with preshared key)
Server address / Server Server name of address OK
IPSec ID / Group name field missing
IPSec key / Shared secret Pre-shared key is it the same?
username username OK
password password OK

So, is there any workaround that I can connect to my LAN using only “native” Windows functions?

Windows 10 VPN - add new connection

I have used Shrewsoft VPN in the past for this scenario. It’s a little old but still works on Windows 10. But yes that needs to be installed as well.
Maybe you can use a Raspberry Pi in your network instead and configure the protocols the right way.

Or do the same but then with a device at work, that you put in between the computer and the network.

Wont work, because windows cant IKEv1 and Frotzbox cant IKEv2. It seems to only work with the extra software.

Now there is another piece of software that can be used: https://en.avm.de/service/vpn/how-to-tips/setting-up-a-vpn-connection-to-fritzbox-in-windows-fritzvpn/

It is also not windows native, and it needs a weird configuration file, you cannot just put in the credentials etc. Why easy, if you can make it complicated?

OP’s question was - is it possible without installing. He has no admin rights to install.

I have just encountered this today and it’s the craziest shit I’ve ever seen.

I can not believe how complicated and terrifying it is, some of the process sounds like it will wipe the fritzbox back to factory?

Why do I need to import a file into the modem itself (!?!!?) There’s an account on there, it works for Android VPN already, I just want to connect to it.

It’s insane how complicated and crazy this, it’s insane.

I can see exactly why I stopped using these things for myself.

You are correct and that is also what you wrote in your first reply.
That is why I wrote that indeed it needs to be installed, and why I gave a suggestion for a possible workaround.
