Hi , I have HP SecPath U200-A and I configure it to make users access internet (PAT) , it is working good.
The second task to create L2TP VPN tunnle for remote users to can access the internal network( 10.16.0.0/16) using L2TP client on windows .
So I added L2TP group with attached settings and create local user .
But when test that on the remote client ,I get the attached error (and note that I test the pc with same connection to another VPN gatway its working)
thanks for your efforts.
