L2TP PSK issue

Hello Community,

I have a strange issue with the L2TP PSK on one Firewall. I set the PSK  in the L2TP configuration on XG. The users can connect and have access to the network. After a while the users are unable to connect. On their Client they get an error message that the connection is not possible. I did some investigations about that and saw that the PSK on the Firewall has changed. When I check preshared key in the L2TP settings I see a long encrypted key starting with "$sfos$....". After I set my PSK again the users can connect. Now the encrypted key is shorter. So something will change the PSK on the firewall.

What is the reason for this behavior?

The Firewall runs on v18-MR5 but I had the same issue with MR4.

Thanks,

Ben

    Hi Ben@Network,

    The issue(NC-72172) with the encrypted PSK for L2TP and IPsec remote access is fixed in the new refresh release of the already released v18 MR5. 

    Thanks,
