I have a VPN that has been configured for a couple months between a clients SonicWall and my ASA 5505. The tunnel have been active with no error messages, but I just started receiving the following error messages. I've contacted the client and he states that nothing has changed (that he is aware of), but I believe something had to be changed to drop the tunnel. I will pass Phase1, but crash on Phase2. Can someone assist me with what these error messages are referencing to? I'm not to sure about SonicWall applicances, but I need to have some idea of where to have him look.
