Notes

VPN: Fix for IKEv2 with Microsoft Windows breaks after 7.6 hours.

VPN connections with IKEv2 and Microsoft Windows’ on-board means are interrupted after exactly 7.6 hours. The error occurs because Microsoft Windows proposes different algorithms during the IKE re-encryption than during the first connection. The problem can be solved with a registry fix by changing changing the value “NegotiateDH2048_AES256” under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters to 1 is set.

At the following link you can find a REG file (registry entry) that adds the registry key. Collax assumes no liability for system errors resulting from this.
