How exactly do we have to changed to fix this with the L2TP over IPSEC settings to do this as I can't find 128 bit anywhere in the profile settings for VPN or L2TP settings on the sonicwall. Truncating to fewer than 128 bits will result in L2TP VPN failing to connect. To make sure that VPN client devices running iOS 14 and macOS Big Sur can connect to your L2TP VPN server, configure the server to truncate the output of the SHA-256 hash to 128 bits. ' Starting with iOS 14 and macOS Big Sur (coming soon), IPsec supports HMAC-SHA-256 with L2TP VPN. SonicWall Mobile Connect is a free app, but requires a concurrent user.

The client provides anytime, anywhere access to critical applications such as email, virtual desktop sessions and other macOS applications. I believe it probably due to the L2TP update they did on there end which now requires us to switch L2TP to SHA-256 to 128 Bit. SonicWall Mobile Connect provides users full network-level access to corporate and academic resources over encrypted SSL VPN connections. We had a user that upgraded there Mac to Monterey and the VPN stopped working.
