IKEv1 VPN sensor not working

Votes:

0

i was using SNMP Cisco ASA VPN Traffic sensor to monitor a connection and it was working, but suddenly the sensor is down even though the VPN connection is working fine with no changes on the firewall or whats so ever error: There is no active connection for this remote IP address. The reason might be an issue with Cisco's SNMP component. The data that PRTG receives from the device is incorrect. To resolve this issue, see https://kb.paessler.com/en/topic/59643. (code: PE123)

knowing i am using IKEv1 for tunneling and its lan to lan when i add the sensor

Hi Adel,

Thank you for your post. You're right, this error is mostly reported with IKEv2 connections.

I order to be able to analyze this further I would like to continue within a dedicated Support Ticket.

Please forward me the following screenshot via mail to [email protected] (please include PAE1300453 within the subject):
- Screenshot of the sensor's "Overview" tab
- Screenshot of the sensor's "Log" tab
- Screenshot of the sensor's "Settings" tab

Thank you very much in advance!

Kind regards,
Andreas Günther
