Remote Access VPN stopped working in ASA 5515 9.1

Level 1

Hi,

 

I have an ASA 5515 with 9.1 set up and everything works, users from inside can use Remote Access VPN to connect to Meraki MX. The I tried to add site-to-site VPN and that break the Remote Access. As temporary solution I stripped everything I added and it still not working.

Any suggestion?

Thanks in advance!

Error message:

My VPN

Can't connect to My VPN

The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiation with the remote computer.

 

Thanks again.

Whenever you face any problems and you are running a firmware that reached end of support  a very long time ago, first update to a suggested release and then test again.

Thanks for the tip, but I don't have the luxury - we only use this box as temporary solution and don't have tech support anymore.

Even without support you can call TAC, reference a security advisory and request a newer fixed software-release.
