Greetings. I'm pretty new to networking and VPN stuff (read: be gentle ;-) and am trying to get a MS VPN client to work w/ the SonicWALL server. I suspect I need to create a SSL cert on the server but not sure. I can connect with a SonicWALL client, but we'd like to use the MS client. When I try to connect I get an 'Error 789' that says, "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer". I have my MS Client configured thus (using Windows XP): Security: - Security Options: * Typical o Require data encryption (have tried it w/ and w/o this but get the same error) - Networking * Type of VPN: L2TP IPSec VPN o Settings - Enable LCP extensions - Enable software compression My Sonic client has the following settings: - User Authentication: 'the peer does not allow saving of username and password' - Peers: one peer defined Any thoughts on what I need to do to overcome the Error 789 when connecting to SonicWALL VPN from a MS client?

Thanks. We'll let you know when a new response is added.

This is very iffy. VPNs are often proprietary. Imagine trying to put a Mercedes diesel truck engine on a BMW motorcycle.

You may need a gateway or some other matching interface or it may be completely impossible. I am not sure there is such a thing as a VPN accepted protocol. This is in contrast to accepted industry standards (or protocols) like 802.11b or CAT6A.
