I'm still getting problems with the above error.
I've setup NMAS for NDS password authentication.
LPO object in C1 looks ok.
Authentication rules look ok, have setup rule to allow all users in
NMAS NDS passwords.
Have followed Craigs book to setup VPN and have also tried adding in
moving rules order and deleting rules but still get the same problem.The audit log has these entries:
NMAS Password box
Failed Receiving Server DH Value
A connection was opened for a VPN client at address
Failed to process NMAS request. NMAS error code = 0xB8004000.
Connection closed for the VPN client at address

Any help appreciated.
