Hi,

I have followed the steps to connect Meraki L2TP VPN in windows, but still facing an error. I am not getting the login window.

Hi, I have got the following error. based on the documentation the adapter is already allowed PAP.

Do you have a dedicated IP or is it behind a NAT.

If it's behind a NAT you can try this.

Registry Adjustment (for NAT network)

If your client or server is behind a router with NAT:

Open the Registry Editor (regedit).

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent.

Create a DWORD AssumeUDPEncapsulationContextOnSendRule and set the value to 2.

Restart the machine.

This is a pretty common issue with the Windows L2TP client and Meraki, so you’re not alone. If the login prompt never appears, the first thing to check is that you’re using L2TP/IPsec with a pre-shared key and that the PSK matches exactly what’s set in the Meraki dashboard. Also make sure your Windows VPN adapter has “Allow these protocols” enabled and that MS-CHAP v2 is checked. If you’re behind NAT, missing the UDP ports 500, 1701, and 4500 will also cause this exact behavior. A quick reboot after setting the registry NAT-T fix often helps too.

Dette er et almindeligt problem med Windows L2TP-klienter, der opretter forbindelse til Meraki. Hvis loginprompten aldrig vises, skal du først dobbelttjekke, at du bruger L2TP/IPsec med den korrekte foruddelte nøgle. Sørg for, at VPN-adapterindstillingerne tillader de rigtige protokoller, og at MS-CHAP v2 er aktiveret. Hvis du er bag NAT, skal du sørge for, at udenlandske online UDP-portene 500, 1701 og 4500 er åbne. Anvendelse af NAT-T-registreringsrettelsen og genstart løser ofte problemet. Ved at følge disse trin får klienten normalt til at spørge og oprette forbindelse korrekt.
