IPSEC-VPN (Mobile-Client) not working after Update to V2.5.2
-
Hello everyone,
a year ago, I created a VPN-IPSec Mobile-Client Setup with IKEv1 using this tutorial
https://docs.netgate.com/pfsense/en/latest/recipes/ipsec-mobile-ikev1-xauth.htmlAfter updating our primary PfSense on our servers, the VPN-Connection fails.
While the Site-to-Site Connection between our datacenters is still working, the Mobile-Client for our employees fails with a "Shared-Secret-incorrect" error, but nothing was changed at the config before the update. This error happens at all our locations, so it seems like its a problem beacause of the update to 2.5.2.
Therefore I had to shutdown the primary PfSense so the Failover Firewalls with an older version of PfSense can take over.
But this is not a permanent solution, so I need a solution for the problem.Thank you for your help!
